             Summary: hbase_stats3.q test fails when paths stored at JDBCStatsUtils.getIdColumnName() are too large
                 Key: HIVE-8744
                 URL: https://issues.apache.org/jira/browse/HIVE-8744
             Project: Hive
          Issue Type: Bug
    Affects Versions: 0.15.0
            Reporter: Sergio Peña
            Assignee: Sergio Peña


This test is related to the bug HIVE-8065 where I am trying to support HDFS encryption. One of the enhancements to support it is to create a .hive-staging directory on the same table directory location where the query is executed.

Now, when running the hbase_stats3.q test from a temporary directory that has a large path, then the new path, a combination of table location + .hive-staging + random temporary subdirectories, is too large to fit into the statistics table, so the path is truncated.

This causes the following error:

We should increment the size of the VARCHAR datatype in order to fix this.
