What does this error mean (java.io.IOException: Hunk timed out while waiting for package=/tmp/splunk/splunk-1/hunk-6.2.2-257696-linux-2.6-x86_64.tgz to be installed)?

Each time I run a Hunk job, I get this error and I'm guessing the IOException comes from not finding the file. We're running this on Yarn, CDH 5.3

You need read/write/execute permissions in the operating system /tmp directory on each DataNode (around 50-100 mb space per DataNode). It stores subset of Hunk ERP binaries and knowledge bundles. If /tmp is mounted without execute permissions please change/set vix.splunk.home.datanode to a different datanode directory or enable /tmp permission and enough space

I'm running against AWS EMR and I get this same error. /tmp is a symlink to /mnt/tmp and has the correct permissions, plenty of space, and is executable. What are other causes of this error?

If you are getting this message, event after having correct permissions and enough space, then issue could be happening because of timeout while copying package to the data nodes. The default timeout for the package copy is 20sec.
Setting for this in Hunk Provider is mentioned below.
vix.splunk.setup.package.setup.timelimit = time limit (in milliseconds)
Try after increasing timeout to 2 minutes.
