I noticed interesting issue today. Not sure if I have the latest master but
it is not older then one day.
I created few indices in cluster, then I shut down the cluster and started
again. During startup I got the following ERROR message in log:
[ERROR][gateway.local ] [Drake, Frank] failed to create index
I shutdown the cluster and started again, this time I did not get this error
but the index was not recognized and created at all. It is simply missing in
cluster status. The index data is still present in /data folder but if I
check the _state folder there are two files: metadata-xx and shards-yy. The
[testindex] is still referenced in shards-yy but not in metadata-xx.
Not sure what went wrong (did not have a DEBUG logging level turned on) but
one of the other indices have alias [testindex]. So there is an index A and
index B having alias A, can this be a problem?
