I recently set up a Hortonworks Sandbox 2.1 in VirtualBox and installed Hunk 6.2 for some lab testing.
As the heading already says, when I start a search, it won't finalize. Hunk tells me x of y events matched and then gets stuck.
I configured my provider according to what Hue and the yarn-site.xml told me and none of the previous questions referring to the same issue helped me.
My search.log gives me 2 errors, I don't understand:
1. java.lang.RuntimeException: Parent search is done. Alive token file does not exist: /opt/hunk/var/run/splunk/dispatch/subsearch_1422460645.44_1422461000.3/alive.token
2. java.lang.RuntimeException: Parent search is done. Found file: /opt/hunk/var/run/splunk/dispatch/1422460645.44/finalize
I already figured it out this morning, when suddenly a "OutOfMemory" exception appeared instead which was way more helpful. Allocating more memory by modifying yarn-site.xml and mapred-site.xml solved the problem.
