Hello Bharath Vissapragada, Csaba Ringhofer, Impala Public Jenkins, I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/11814 to look at the new patch set (#6). Change subject: IMPALA-7586: fix predicate pushdown of escaped strings ...................................................................... IMPALA-7586: fix predicate pushdown of escaped strings This fixes a class of bugs where the planner incorrectly uses the raw string from the parser instead of the unescaped string. This occurs in several places that push predicates down to the storage layer: * Kudu scans * HBase scans * Data source scans There are some more complex issues with escapes and the LIKE predicate that are tracked separately by IMPALA-2422. This also uncovered a different issue with RCFiles that is tracked by IMPALA-7778 and is worked around by the tests added. In order to make bugs like this more obvious in future, I renamed getValue() to getValueWithOriginalEscapes(). Testing: Added regression test that tests handling of backslash escapes on all file formats. I did not add a regression test for the data source bug since it seems to require some major modification of the data source test infrastructure.
