Cluster State Yellow: 2 shards initializing with multiple failed attempts: IllegalArgumentException [ReleasableBytesStreamOutput cannot hold more than 2GB of data

Hi @Sarit_Ghosh,

From the stack trace you have provided it looks like the returned result set is larger than 2G. This is larger than the amount that Elasticsearch can return in a single request. Have you been able to find out the query being run that is triggering this error?

I would recommend having a look at this related thread which does give some suggestions on diagnosing the problem further down.
