pipes does not allow jobconf values containing commas
-----------------------------------------------------
Key: HADOOP-6006
URL: https://issues.apache.org/jira/browse/HADOOP-6006
Project: Hadoop Core
Issue Type: Bug
Components: pipes
Affects Versions: 0.18.3
Reporter: Christian Kunz
Currently hadoop pipes does not allow a
-jobconf <key>=<value>,<key>=<value>...
commandline parameter with one or more commas in one of the values of the
key-value pairs.
One use case is key=mapred.join.expr, where the value is required to have
commas.
And it is not always convenient to add this to a configuration file.
Submitter.java could easily be changed to check for backslash in front of a
comma before using it as a delimiter.
