Prabhu Joseph updated SPARK-24008: ---------------------------------- Attachment: Repro > SQL/Hive Context fails with NullPointerException > ------------------------------------------------- > > Key: SPARK-24008 > URL: https://issues.apache.org/jira/browse/SPARK-24008 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.6.3 > Reporter: Prabhu Joseph > Priority: Major > Attachments: Repro > > > SQL / Hive Context fails with NullPointerException while getting > configuration from SQLConf. This happens when the MemoryStore is filled with > lot of broadcast and started dropping and then SQL / Hive Context is created > and broadcast. When using this Context to access a table fails with below > NullPointerException. > Repro is attached - the Spark Example which fills the MemoryStore with > broadcasts and then creates and accesses a SQL Context. > {code} > java.lang.NullPointerException > at org.apache.spark.sql.SQLConf.getConf(SQLConf.scala:638) > at > org.apache.spark.sql.SQLConf.defaultDataSourceName(SQLConf.scala:558) > at > org.apache.spark.sql.DataFrameReader.<init>(DataFrameReader.scala:362) > at org.apache.spark.sql.SQLContext.read(SQLContext.scala:623) > at SparkHiveExample$.main(SparkHiveExample.scala:76) > at SparkHiveExample.main(SparkHiveExample.scala) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at > sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) > at > sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) > at java.lang.reflect.Method.invoke(Method.java:498) > 18/04/06 14:17:42 ERROR ApplicationMaster: User class threw exception: > java.lang.NullPointerException > java.lang.NullPointerException > at org.apache.spark.sql.SQLConf.getConf(SQLConf.scala:638) > at org.apache.spark.sql.SQLContext.getConf(SQLContext.scala:153) > at > org.apache.spark.sql.hive.HiveContext.hiveMetastoreVersion(HiveContext.scala:166) > > at > org.apache.spark.sql.hive.HiveContext.metadataHive$lzycompute(HiveContext.scala:258) > > at org.apache.spark.sql.hive.HiveContext.metadataHive(HiveContext.scala:255) > at > org.apache.spark.sql.hive.HiveContext$$anon$2.<init>(HiveContext.scala:475) > at > org.apache.spark.sql.hive.HiveContext.catalog$lzycompute(HiveContext.scala:475) > > at org.apache.spark.sql.hive.HiveContext.catalog(HiveContext.scala:474) > at org.apache.spark.sql.hive.HiveContext.catalog(HiveContext.scala:90) > at org.apache.spark.sql.SQLContext.table(SQLContext.scala:831) > at org.apache.spark.sql.SQLContext.table(SQLContext.scala:827) > {code} > MemoryStore got filled and started dropping the blocks. > {code} > 18/04/17 08:03:43 INFO MemoryStore: 2 blocks selected for dropping > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_14 stored as values in > memory (estimated size 78.1 MB, free 64.4 MB) > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_14_piece0 stored as bytes > in memory (estimated size 1522.0 B, free 64.4 MB) > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_15 stored as values in > memory (estimated size 350.9 KB, free 64.1 MB) > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_15_piece0 stored as bytes > in memory (estimated size 29.9 KB, free 64.0 MB) > 18/04/17 08:03:43 INFO MemoryStore: 10 blocks selected for dropping > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_16 stored as values in > memory (estimated size 78.1 MB, free 64.7 MB) > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_16_piece0 stored as bytes > in memory (estimated size 1522.0 B, free 64.7 MB) > 18/04/17 08:03:43 INFO MemoryStore: Block broadcast_1 stored as values in > memory (estimated size 136.0 B, free 64.7 MB) > 18/04/17 08:03:44 INFO MemoryStore: MemoryStore cleared > 18/04/17 08:03:20 INFO MemoryStore: MemoryStore started with capacity 511.1 MB > 18/04/17 08:03:44 INFO MemoryStore: MemoryStore cleared > 18/04/17 08:03:57 INFO MemoryStore: MemoryStore started with capacity 511.1 MB > 18/04/17 08:04:23 INFO MemoryStore: MemoryStore cleared > {code} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
