I installed HUNK to work with local hadoop cluster (hadoop 2.3.0 YARN). The following error happened when running search command "index=virtual_index_name".

[smllog] Error while running external process, return_code=126. See search.log for more info

I checked the content of search.log and found no error. The following is something may be related.

Error running external process normally means Hunk cannot find your Hadoop or Java processes.
So if your Hadoop processes is '/usr/bin/hadoop' in the Hunk configuration you will need to put ' /usr ' (Hunk will add /bin/hadoop)

Thank you very much. You saved me a lot of time.
I set java home to /usr/bin/java. After I changed it to /usr/java/jdk, it works.
