Thanks, Josh. I submitted the issue, which can be found at: https://issues.apache.org/jira/browse/PHOENIX-2503
Multiple Java NoClass/Method Errors with Spark and Phoenix From: Josh Mahonin [mailto:jmaho...@gmail.com] Sent: Wednesday, December 09, 2015 1:15 PM To: user@phoenix.apache.org Subject: Re: [EXTERNAL] Re: Confusion Installing Phoenix Spark Plugin / Various Errors Hi Jonathan, Thanks, I'm digging into this as we speak. That SPARK-8332 issue looks like the same issue, and to quote one of the comments in that issue 'Classpath hell is hell'. What is interesting is that the unit tests in Phoenix 4.6.0 successfully run against Spark 1.5.2 [1], so I wonder if this is issue is specific to the spark-shell. You may have some success compiling your app as an assembly JAR and submitting it to a Spark cluster instead. Could you do me a favour and file a JIRA ticket for this, and copy all the relevant information you've posted there? Thanks!

It looks like when I add the Phoenix Client JAR to Spark, it causes Spark to fail: spark.executor.extraClassPath /usr/local/phoenix/phoenix-4.6.0-HBase-1.1-client.jar spark.driver.extraClassPath /usr/local/phoenix/phoenix-4.6.0-HBase-1.1-client.jar After adding this JAR, I get the following error when excuting the following command: scala> val textFile = sc.textFile("README.md") java.lang.NoSuchMethodError: com.fasterxml.jackson.module.scala.deser.BigDecimalDeserializer$.handledType()Ljava/lang/Class; at com.fasterxml.jackson.module.scala.deser.NumberDeserializers$.<init>(ScalaNumberDeserializersModule.scala:49) at com.fasterxml.jackson.module.scala.deser.NumberDeserializers$.<clinit>(ScalaNumberDeserializersModule.scala) As you can see, adding this phoenix JAR is breaking other Spark functionality for me. My naïve guess is that there is a different version of the Jackson FasterXML classes packaged inside phoenix-4.6.0-HBase-1.1-client.jar that is breaking Spark. Have you seen anything like this before?

I'd like to dig into what the root cause is, but it might be optimistic to think I'll be able to get to that any time soon. I'll try get the docs updated today.

However, by separately downloading Hadoop 2.6 and Spark without Hadoop, the errors went away. -Jonathan From: Josh Mahonin [mailto:jmaho...@gmail.com<mailto:jmaho...@gmail.com>] Sent: Wednesday, December 09, 2015 5:57 AM To: user@phoenix.apache.org<mailto:user@phoenix.apache.org> Subject: Re: [EXTERNAL] Re: Confusion Installing Phoenix Spark Plugin / Various Errors Hi Jonathan, Thanks for the information. If you're able, could you also try the 'SPARK_CLASSPATH' environment variable instead of the spark-defaults.conf setting, and let us know if that works? Also the exact Spark package you're using would be helpful as well (from source, prebuilt for 2.6+, 2.4+, CDH, etc.) Thanks, Josh On Wed, Dec 9, 2015 at 12:08 AM, Cox, Jonathan A <ja...@sandia.gov<mailto:ja...@sandia.gov>> wrote: Alright, I reproduced what you did exactly, and it now works. The problem is that the Phoenix client JAR is not working correctly with the Spark builds that include Hadoop. When I downloaded the Spark build with user provided Hadoop, and also installed Hadoop manually, Spark works with Phoenix correctly! Thank you much, Jonathan Sent from my iPhone On Dec 8, 2015, at 8:54 PM, Josh Mahonin <jmaho...@gmail.com<mailto:jmaho...@gmail.com>> wrote: Hi Jonathan, Spark only needs the client JAR. It contains all the other Phoenix dependencies as well. I'm not sure exactly what the issue you're seeing is. I just downloaded and extracted fresh copies of Spark 1.5.2 (pre-built with user-provided Hadoop), and the latest Phoenix 4.6.0 binary release. I copied the 'phoenix-4.6.0-HBase-1.1-client.jar' to /tmp and created a 'spark-defaults.conf' in the 'conf' folder of the Spark install with the following: spark.executor.extraClassPath /tmp/phoenix-4.6.0-HBase-1.1-client.jar spark.driver.extraClassPath /tmp/phoenix-4.6.0-HBase-1.1-client.jar I then launched the 'spark-shell', and was able to execute: import org.apache.phoenix.spark._ From there, you should be able to use the methods provided by the phoenix-spark integration within the Spark shell.

I’m using Spark 1.5.2, HBase 1.1.2 and Phoenix 4.6.0 with a standalone install (no HDFS or cluster) with Debian Linux 8 (Jessie) x64. I’m also using Java 1.8.0_40. The instructions state: 1. Ensure that all requisite Phoenix / HBase platform dependencies are available on the classpath for the Spark executors and drivers 2. One method is to add the phoenix-4.4.0-client.jar to ‘SPARK_CLASSPATH’ in spark-env.sh, or setting both ‘spark.executor.extraClassPath’ and ‘spark.driver.extraClassPath’ in spark-defaults.conf First off, what are “all requisite Phoenix / HBase platform dependencies”? #2 suggests that all I need to do is add ‘phoenix-4.6.0-HBase-1.1-client.jar’ to Spark’s class path. But what about ‘phoenix-spark-4.6.0-HBase-1.1.jar’ or ‘phoenix-core-4.6.0-HBase-1.1.jar’? Do either of these (or anything else) need to be added to Spark’s class path? Secondly, if I follow the instructions exactly, and add only ‘phoenix-4.6.0-HBase-1.1-client.jar’ to ‘spark-defaults.conf’: spark.executor.extraClassPath /usr/local/phoenix/phoenix-4.6.0-HBase-1.1-client.jar spark.driver.extraClassPath /usr/local/phoenix/phoenix-4.6.0-HBase-1.1-client.jar Then I get the following error when starting the interactive Spark shell with ‘spark-shell’: 15/12/08 18:38:05 WARN ObjectStore: Version information not found in metastore. hive.metastore.schema.verification is not enabled so recording the schema version 1.2.0 15/12/08 18:38:05 WARN ObjectStore: Failed to get database default, returning NoSuchObjectException 15/12/08 18:38:05 WARN Hive: Failed to access metastore.

However, if I include only the ‘phoenix-spark-4.6.0-HBase-1.1.jar’, spark-shell seems so launch without error. Nevertheless, if I then try the simple tutorial commands in spark-shell, I get the following: Spark output: SQL context available as sqlContext. scala >> import org.apache.spark.SparkContext import org.apache.spark.sql.SQLContext import org.apache.phoenix.spark._ val sqlContext = new SQLContext(sc) val df = sqlContext.load("org.apache.phoenix.spark", Map("table" -> "TABLE1", "zkUrl" -> "phoenix-server:2181") Spark error: java.lang.NoClassDefFoundError: org/apache/hadoop/hbase/HBaseConfiguration at org.apache.phoenix.spark.PhoenixRDD.getPhoenixConfiguration(PhoenixRDD.scala:71) at org.apache.phoenix.spark.PhoenixRDD.phoenixConf$lzycompute(PhoenixRDD.scala:39) at org.apache.phoenix.spark.PhoenixRDD.phoenixConf(PhoenixRDD.scala:38) at org.apache.phoenix.spark.PhoenixRDD.<init>(PhoenixRDD.scala:42) at org.apache.phoenix.spark.PhoenixRelation.schema(PhoenixRelation.scala:50) at org.apache.spark.sql.execution.datasources.LogicalRelation.<init>(LogicalRelation.scala:37) at org.apache.spark.sql.DataFrameReader.load(DataFrameReader.scala:120) This final error seems similar to the one in mailing list post Phoenix-spark : NoClassDefFoundError: HBaseConfiguration<http://mail-archives.apache.org/mod_mbox/phoenix-user/201511.mbox/ajax/%3CCAKwwsRSEJHkotiF28kzumDZM6kgBVeTJNGUoJnZcLiuEGCTjHQ%40mail.gmail.com%3E> < http://mail-archives.apache.org/mod_mbox/phoenix-user/201511.mbox/ajax/%3CCAKwwsRSEJHkotiF28kzumDZM6kgBVeTJNGUoJnZcLiuEGCTjHQ%40mail.gmail.com%3E>. But the question does not seem to have been answered satisfactory. Also note, if I include all three JARs, as he did, I get an error when launching spark-shell. Can you please clarify what is the proper way to install and configure Phoenix with Spark? Sincerely, Jonathan
