> Key: AMBARI-21730
> URL: https://issues.apache.org/jira/browse/AMBARI-21730
> Project: Ambari
> Issue Type: Bug
> Affects Versions: 2.5.0, 2.5.1
> Reporter: Xabriel J Collazo Mojica
>
> Ambari 2.5+ sets the following Hive Interactive flag by default to:
> {{hive.llap.execution.mode=only}}
> This mode breaks compatibility with StorageHander based tables. For example,
> HBase tables like these fail:
> CREATE TABLE hbase_table_1(key int, value string)
> STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler'
> WITH SERDEPROPERTIES ("hbase.columns.mapping" = ":key,cf1:val")
> TBLPROPERTIES ("hbase.table.name" = "xyz",
> "hbase.mapred.output.outputtable" = "xyz");
> With a stack trace like:
> 0: jdbc:hive2://intel68bvt2.fyre.ibm.com:2181> INSERT OVERWRITE TABLE
> hbase_table_1 SELECT * FROM hbase_table_1;
> INFO : Compiling
> command(queryId=hive_20170814172300_b01cbd64-f790-468b-855c-2ff8224f4fc0):
> INSERT OVERWRITE TABLE hbase_table_1 SELECT * FROM hbase_table_1
> ....
> INFO : Dag name: INSERT OVERWRITE TABLE hbase...hbase_table_1(Stage-3)
> INFO : Dag submit failed due to There is conflicting local resource
