Subject: Re: Altered sql table (adding new columns) does not reflect in Spark
shell
Hi,
Yes, I can confirm that this is the issue. I filed next ticket for it:
https://issues.apache.org/jira/browse/IGNITE-12159

Hi,
I created and altered the table using the following queries:
a. CREATE TABLE person (id LONG, name VARCHAR(64), age LONG, city_id DOUBLE,
zip_code LONG, PRIMARY KEY (name)) WITH "backups=1"
b. ALTER TABLE person ADD COLUMN (first_name VARCHAR(64), last_name VARCHAR(64))
*The changes (columns added from above Alter table SQL) are correct when
verified from GridGain.
However, when I use Spark shell, couldn't find the columns added through Alter
table SQL (above (b) query).
Is there any configuration that I am missing? (Attached ignite-config file for
reference)
Executed the following commands in Spark shell:
Step 1: Connected to Spark shell:
/usr/hdp/2.6.5.1100-53/spark2/bin/spark-shell --jars
/opt/jar/ignite-core-2.7.0.jar,/opt/jar/ignite-spark-2.7.0.jar,/opt/jar/ignite-spring-2.7.0.jar,"/opt/jar/commons-logging-1.1.3.jar","/opt/jar/spark-core_2.11-2.3.0.jar","/opt/jar/spring-core-4.3.18.RELEASE.jar","/opt/jar/spring-beans-4.3.18.RELEASE.jar","/opt/jar/spring-aop-4.3.18.RELEASE.jar","/opt/jar/spring-context-4.3.18.RELEASE.jar","/opt/jar/spring-tx-4.3.18.RELEASE.jar","/opt/jar/spring-jdbc-4.3.18.RELEASE.jar","/opt/jar/spring-expression-4.3.18.RELEASE.jar","/opt/jar/cache-api-1.0.0.jar","/opt/jar/annotations-13.0.jar","/opt/jar/ignite-shmem-1.0.0.jar","/opt/jar/ignite-indexing-2.7.0.jar","/opt/jar/lucene-analyzers-common-7.4.0.jar","/opt/jar/lucene-core-7.4.0.jar","/opt/jar/h2-1.4.197.jar","/opt/jar/commons-codec-1.11.jar","/opt/jar/lucene-queryparser-7.4.0.jar","/opt/jar/spark-sql_2.11-2.3.0.jar"
--driver-memory 4g
Step 2: Ran the import statements:
import org.apache.ignite.{ Ignite, Ignition }
import org.apache.ignite.spark.IgniteDataFrameSettings._
import org.apache.spark.sql.{DataFrame, Row, SQLContext}
val CONFIG = "file:///opt/ignite-config.xml"
Step3: Read a table
var df = spark.read.format(FORMAT_IGNITE).option(OPTION_CONFIG_FILE,
CONFIG).option(OPTION_TABLE, "person").load()
df.show();
