Kanna Karanam commented on HIVE-3127: ------------------------------------- @Edward - Thanks for helping me understand the hive better. I couldn’t figure out the caller of for BlockMergeTask::main anywhere in the code. Thanks. > Don’t pass–hconf values as command line arguments to child JVM to avoid > command line exceeding char limit on windows > -------------------------------------------------------------------------------------------------------------------- > > Key: HIVE-3127 > URL: https://issues.apache.org/jira/browse/HIVE-3127 > Project: Hive > Issue Type: Bug > Components: Configuration, Windows > Affects Versions: 0.9.0, 0.10.0, 0.9.1 > Reporter: Kanna Karanam > Assignee: Kanna Karanam > Labels: Windows > Fix For: 0.10.0 > > Attachments: HIVE-3127.1.patch.txt, HIVE-3127.2.patch.txt, > HIVE-3127.3.patch.txt > > > The maximum length of the DOS command string is 8191 characters (in Windows > latest versions http://support.microsoft.com/kb/830473). This limit will be > exceeded easily when it appends individual –hconf values to the command > string. To work around this problem, Write all changed hconf values to a temp > file and pass the temp file path to the child jvm to read and initialize the > -hconf parameters from file. -- This message is automatically generated by JIRA.
