Hello Elasticsearch-Hadoop user
I got a little bit complicated situation. I am trying to back up Elasticsearch data to Hive through parquet file format with schema. Writing to parquet file was ok but while registering its schema to Hive metadata store, I got the following error:
Caused by: org.apache.hive.service.cli.HiveSQLException: Error while compiling statement: FAILED: ParseException line 1:208 mismatched input '-' expecting > near 'timestamp' in struct type
Somebody who's in charge of hadoop/hive cluster told me this problem is already known in parquet-hive incompatibility problem and I should've used long or string type for date format but I cannot control in Elasticsearch-hadoop connector.
Is there any hidden feature in elasticsearch-hadoop connector to convert date format to long or string type? Otherwise, if I have to touch source codes and build my own library, may I have some advices on touching source codes?
