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"}
