[jira] [Updated] (HADOOP-11371) Shell#runCommand may miss output on stderr

     [ https://issues.apache.org/jira/browse/HADOOP-11371?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gera Shegalov updated HADOOP-11371:
-----------------------------------
    Status: Open  (was: Patch Available)

Hi [~djp], cancelling the patch since it no longer applies. Since my major concern turned to be a non-Issue with OpenJDK which is our JVM based off, we don't need it at the moment.

> Shell#runCommand uses buffered reader to read complete lines. Hence, if the output is not terminated by newline or the thread was interrupted before new line was produced by the child process, this last portion is not consumed.
