Description

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.
