Subject [jira] [Commented] (CASSANDRA-4880) Endless loop flushing+compacting system/schema_keyspaces and system/schema_columnfamilies
Date Fri, 09 Nov 2012 02:38:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-4880?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13493692#comment-13493692
] 

Mina Naguib commented on CASSANDRA-4880:
----------------------------------------

[~xedin] Here's mine (after some very minor name obfuscation):

{code}
[default@system] list schema_keyspaces;
Using default limit of 100
Using default column limit of 100
-------------------
RowKey: AdKS
=> (column=durable_writes, value=true, timestamp=1336233003898)
=> (column=name, value=AdKS, timestamp=1336233003898)
=> (column=strategy_class, value=org.apache.cassandra.locator.NetworkTopologyStrategy,
timestamp=1336233003898)
=> (column=strategy_options, value={"DCMTL":"2","DCLA":"2","DCLON":"2"}, timestamp=1336233003898)

1 Row Returned.
Elapsed time: 3 msec(s).
{code}

Tomorrow I'll run a test with cassandra 1.1.6 + CASSANDRA-4837 just to add a second vote to
Brandon's test whether it helps or not.

> After upgrading a node from 1.1.2 to 1.1.6, the startup sequence entered a loop as seen
here:
> http://mina.naguib.ca/misc/cassandra_116_startup_loop.txt
> Stopping and starting the node entered the same loop.
> Reverting back to 1.1.2 started successfully.
