compute incremental stats fail for new partition

[#1]

Hi,

I am using impala 2.5 with cdh 5.7.3

I trigger daily a compute incremental stats and it always worked until now, but today I got an exception.

The table is partitioned by a `date` column

When I do a profile, I get: 

Query Runtime Profile:
Query (id=fb406e80eb5f914e:99174c15db345bae):

any idea why the date get suddently double escaped? 

thanks

Thanks for reporting this issue! Sorry for the trouble.

I was able to reproduce the issue and can confirm this is a regression from previous Impala versions.

I filed https://issues.cloudera.org/browse/IMPALA-4170 to track progress on the issue.
