Chetan Bhat created CARBONDATA-1782:
---------------------------------------
Summary: (Carbon1.3.0 - Streaming) Select regexp_extract from
table with where clause having is null throws indexoutofbounds exception
Key: CARBONDATA-1782
URL: https://issues.apache.org/jira/browse/CARBONDATA-1782
Project: CarbonData
Issue Type: Bug
Components: data-query
Affects Versions: 1.3.0
Environment: 3 node ant cluster
Reporter: Chetan Bhat
Steps :
Thrift server is started using the command - bin/spark-submit --master
yarn-client --executor-memory 10G --executor-cores 5 --driver-memory 5G
--num-executors 3 --class
org.apache.carbondata.spark.thriftserver.CarbonThriftServer
/srv/spark2.2Bigdata/install/spark/sparkJdbc/carbonlib/carbondata_2.11-1.3.0-SNAPSHOT-shade-hadoop2.7.2.jar
"hdfs://hacluster/user/sparkhive/warehouse"
Spark shell is launched using the command - bin/spark-shell --master
yarn-client --executor-memory 10G --executor-cores 5 --driver-memory 5G
--num-executors 3 --jars
/srv/spark2.2Bigdata/install/spark/sparkJdbc/carbonlib/carbondata_2.11-1.3.0-SNAPSHOT-shade-hadoop2.7.2.jar
>From Spark shell the streaming table is created and data is loaded to the
>streaming table.
