Kanna Karanam created HIVE-3127:
-----------------------------------
Summary: 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
Affects Versions: 0.9.0, 0.10.0, 0.9.1
Reporter: Kanna Karanam
Fix For: 0.10.0
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.
