Jinfeng Ni commented on DRILL-1488:
-----------------------------------
The restriction of 128 for sql identifier comes from Optiq. If we want to
support an identifier with length larger than 128, we have to make the SQL
parser configurable, so that we could specify the max length for sql identifier
in Drill.
> Limit on file name in sql query is too small

> Key: DRILL-1488
> URL: https://issues.apache.org/jira/browse/DRILL-1488
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 0.6.0
> Reporter: Parth Chandra
> Assignee: Jinfeng Ni
> Fix For: 0.7.0
>
>
> While building from the release tarball, unit test fail if you build from a
> directory that is nested several levels deep such that the full path to some
> of the test data files is longer than 128 characters.
> The limit appears to be very small and should be increased.
> One of the errors during the build that illustrates the problem:
> testTextJoin(org.apache.drill.TestExampleQueries) Time elapsed: 0.011 sec
> <<< ERROR!
> org.apache.drill.exec.rpc.RpcException: Failure while parsing sql. Length of
> identifier
> 'file:/Users/pchandra/work/drill-release/apache-drill-0.6.0-incubating-src/exec/java-exec/target/test-classes/store/text/data/nations.csv'
> must be less than or equal to 128 characters
