Description

I'm using SolrCloud. When I'm trying to create index snapshot - exception occurs:
INFO: [test] webapp=/solr path=/replication params=

{command=backup&numberToKeep=1}

status=0 QTime=1

SEVERE: Exception while creating snapshot
java.io.FileNotFoundException: File /solr/cores/test/data/index/segments_g does not exist
at org.apache.solr.handler.SnapShooter$FileCopier.copyFile(SnapShooter.java:194)

at org.apache.solr.handler.SnapShooter.createSnapshot(SnapShooter.java:105)
at org.apache.solr.handler.SnapShooter$1.run(SnapShooter.java:78)

Issue occurs randomly. Reloading core usually helps, but sometimes core has to be reloaded couple of times to make snapshot possible.
