---------------------------------------
Kanna,
Your missing something. The BlockMergeTask ask uses -jobconf . You will need
to patch that as well.
[edward@tablitha trunk]$ grep -R '\-jobconf' ./*
{noformat}
./ql/src/java/org/apache/hadoop/hive/ql/io/rcfile/merge/BlockMergeTask.java:
} else if (args[i].equals("-jobconf")) {
{noformat}
> Don’t pass–hconf values as command line arguments to child JVM to avoid
> command line exceeding char limit on windows

> 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.
