Mapr file locking problems

We ran into this having LucidWorks installed on Mapr filesystem.

Lock obtain timed out: NativeFSLock@/mapr/CTE_POC/var/lws/local/ctebd01.qualcomm.com/LucidWorks/LucidWorksSearch/data/solr/cores/LucidWorksLogs/data/index/write.lock: java.io.IOException: Input/output error

We were able to get this going by changing the solrconfig.xml to:

<lockType>simple</lockType>
<unlockonstartup>true</unlockonstartup>


We still had problems with the sqlite database being locked for the LucidWorks UI, however, that is something that Mapr is looking at.
