These methods are Hive = related, but the variable name does not look it is specific for Hive. > Also, the above variable is not on HiveConf nor used anywhere else. I jus= t found a reference on the Hadoop MR1 code. > I'd like to propose the deprecation of {{mapred.dfsclient.parallelism.max= }}, and use a different variable name, such as {{hive.get.input.listing.num= .threads}}, that reflects the intention of the variable. The removal of the= old variable might happen on Hive 3.x -- This message was sent by Atlassian JIRA (v6.3.15#6346)
