[jira] [Commented] (SPARK-20880) When spark SQL is used with
Avro-backed HIVE tables, NPE from
org.apache.hadoop.hive.serde2.avro.AvroObjectInspectorGenerator.supportedCategories.

> Key: SPARK-20880
> URL: https://issues.apache.org/jira/browse/SPARK-20880
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.2.0
> Reporter: Vinod KC
> Priority: Minor
>
> When spark SQL is used with Avro-backed HIVE tables, intermittently getting NPE from org.apache.hadoop.hive.serde2.avro.AvroObjectInspectorGenerator.supportedCategories.
> Root cause is due race condition in hive 1.2.1 jar used in Spark SQL .
> In HIVE 2.2 this issue has been fixed (HIVE JIRA: https://issues.apache.org/jira/browse/HIVE-16175. ), since Spark is still using Hive 1.2.1 jars we are still getting into race condition.
> One workaround is to run Spark with a single task per executor, however it will slow down the jobs.
