-------------------------------------
Summary: Unexplained inconsistent data with Cassandra 2.1
Key: CASSANDRA-10801
URL: https://issues.apache.org/jira/browse/CASSANDRA-10801
Project: Cassandra
Issue Type: Bug
Reporter: Imri Zvik
We are using weird behavior which we cannot explain.
We have a CF, with RF=3, and we are writing and reading data to it with
consistency level of ONE.
For some reason, we see inconsistent results when querying for data.
Even for rows that were written a day ago, we're seeing inconsistent results (1
replca has the data, the two others don't).
Now, I would expect to see timeouts/dropped mutations, but all relevant
counters are not advancing, and I would also expect hints to fix this
inconsistency within minutes, but yet it doesn't.

cqlsh:testing> SELECT WRITETIME(last_update),site_id, tree_id, individual_id,
last_update FROM testcf WHERE site_id = 229673621 AND tree_id = 9 AND
individual_id = 9032483;
writetime(last_update) | site_id | tree_id | individual_id | last_update
