Change subject: IMPALA-5237: support custom string in date/time format ...................................................................... IMPALA-5237: support custom string in date/time format Impala does not represent a custom string at date/time format. For example, addtional custom string between the patterns(e.g. HH\'H\' => 11H) Hive supports this feature, so user wants to get a same result from Impala. By the way, Impala returns a different result as below. * Hive > select from_unixtime(1492677564, 'HH\'H\' mm\'M\' ss\'S\''); 08H 39M 24S * Impala > select from_unixtime(1492677564, 'HH\'H\' mm\'M\' ss\'S\''); 08'8' 39'4' 24'0' The change affects the format pattern for from_unixtime/from_timestamp. There is one intentional difference between Hive and Impala. In Impala, the format string should have any date or time patten as below. * Hive > select from_unixtime(0, '\'Hello world!\''); Hello world! * Impala > select from_unixtime(0, '\'Hello world!\''); Bad date/time conversion format: 'Hello world!' Testing: Add unit tests for working and nonworking cases Change-Id: Ie34055ac695748bcfb110bfa6ed5308f469ea178 --- M be/src/exprs/expr-test.cc M be/src/runtime/timestamp-parse-util.cc 2 files changed, 28 insertions(+), 0 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/08/8508/1 -- To view, visit http://gerrit.cloudera.org:8080/8508 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: Ie34055ac695748bcfb110bfa6ed5308f469ea178 Gerrit-Change-Number: 8508 Gerrit-PatchSet: 1 Gerrit-Owner: Kim Jin Chul <jinc...@gmail.com>
