ASF GitHub Bot commented on TRAFODION-2465   Re: UPDATE STATS failure on Hive table with long varchars GitHub user DaveBirdsall opened a pull request: https://github.com/apache/incubator-trafodion/pull/938 TRAFODION-2465 Fix two bugs This set of changes fixes two problems (both introduced by me): 1. When UPDATE STATISTICS retries a statement, and the statement continues to fail, the error diagnostics are incorrect. The root cause of the error is not reported, and some irrelevant errors are reported (i.e. 8609, error on transaction rollback, which happens because the Executor sometimes has already rolled back the transaction when UPDATE STATISTICS attempts a ROLLBACK after a statement failure). This bug was introduced when I rewrote the retry logic in JIRA TRAFODION-2341 . My unit test was not thorough enough. (ustat/hs_cli.cpp) 2. Performing UPDATE STATISTICS ON EXISTING COLUMNS PERSISTENT would fail on Hive tables with varchar columns over 200000 characters long. I fixed a similar issue in JIRA TRAFODION-2322 , but failed to notice that this issue existed separately in the ON EXISTING COLUMNS code path. (ustat/hs_parser.cpp).
