Hello everyone, I'm seeing intermittent failures using Elasticsearch v
0.16.0. The same query can work and fail. There may be some
correlation with a bulk load running simultaneously. Has anyone seen
similar behavior?
Here's my query (this is a histogram, but the same query w/o the
facets will exhibit the same problem)
{"filter":{"and":[{"terms":{"forum_id":[2]}},{"query":{"query_string":
{"default_field":"body","query":"testing"}}}]},"facets":{"histo1":
{"date_histogram":{"field":"date","interval":"7d"}}}}'
Here's the error from elastic search:
{"error":"SearchPhaseExecutionException[Failed to execute phase
[query], total failure; shardFailures {[2ZvjA8pITz2jpyJYq1kinw]
[landscape][0]: QueryPhaseExecutionException[[landscape][0]:

And a slice of the elastic search log file (this NPE can happen even
when the query returns successfully)
