[jira] [Updated] (CASSANDRA-6981) java.io.EOFException from
Cassandra when doing select
[ https://issues.apache.org/jira/browse/CASSANDRA-6981?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Martin Bligh updated CASSANDRA-6981:
------------------------------------
Description:
Cassandra 2.06, Oracle Java version "1.7.0_51", Linux Mint 16
I have a cassandra keyspace with about 12 tables that are all the same.
If I load 100,000 rows or so into a couple of those tables in Cassandra, it works fine.
If I load a larger dataset, after a while one of the tables won't do lookups any more (not always the same one).
SELECT recv_time,symbol from table6 where mid='S-AUR01-20140324A-1221';
results in "Request did not complete within rpc_timeout."
where "mid" is the primary key (varchar). If I look at the logs, it has an EOFException ... presumably it's running out of some resource (it's definitely not out of disk space)
Sometimes it does this on secondary indexes too: dropping and rebuilding the index will fix it for a while. When it's broken, it seems like only one particular lookup key causes timeouts (and the EOFException every time) - other lookups work fine. I presume the index is corrupt somehow.
