KUDU-3401 Unable to query Kudu tables from Hive with Kudu HMS
Integration enabled
Hive queries on Kudu Tables were failing with the following stack trace:
ERROR : Failed
org.apache.hadoop.hive.metastore.api.MetaException:
java.lang.ClassNotFoundException Class not found
at
org.apache.hadoop.hive.metastore.HiveMetaStoreUtils.getDeserializer(HiveMetaStoreUtils.java:98)
at
org.apache.hadoop.hive.metastore.HiveMetaStoreUtils.getDeserializer(HiveMetaStoreUtils.java:77)
at
org.apache.hadoop.hive.ql.metadata.Table.getDeserializerFromMetaStore(Table.java:331)
The issue was due to the Kudu Hms Client not sending the fields required
by Hive, namely the Input/Outputformat and Serialization library for the
created table when making a create table request. Thus, running queries through
Hive on Kudu tables would fail due to these fields missing in the Hive Database.
This patch adds the missing Input/Output formats and Serialization
library to table creation with Kudu HMS Integration.The patch also extends
the current test cases to cover added fields. Manually tested on a
seperate cluster, confirmed the missing data is sent and written to the
Hive Database.
