solrcloud shard splitting with lock type native

["calin.grecu" <ca...@gmail.com>]

Hi there,

Shard splitting seems to fail if the lock type is native. Here is my config
setting:
  <indexConfig> 
    <lockType>native</lockType>
	<writeLockTimeout>1000</writeLockTimeout>
  </indexConfig>


Shard splitting works if i set the lock type to single or none. However,
after splitting, i am not able to set the lock type back to native, which is
the default. 

Here is the log for when i try to split and using lock type native:

OverseerCollectionProcessor.processMessage : splitshard , {
  "operation":"splitshard",
  "shard":"shard1",
  "collection":"mycollection",
  "async":"myhandle11"}
