Subject [jira] Commented: (CASSANDRA-1012) Problems reading remote rows in trunk?
Date Thu, 22 Apr 2010 21:46:54 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-1012?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12860034#action_12860034
] 

Jonathan Ellis commented on CASSANDRA-1012:
-------------------------------------------

so these logs are saying:

you did a write to machine1,  it wrote the data to itself.

when you did a read from machine1 it read the data from itself.

when you did a read from machine2 it sent a request to machine1 for the data, and got a response
back.

> I've run into a problem with my small 3 node cluster where quorum reads do not return
anything. I'm inserting 10 rows into a fresh database with replication factor 3. I've inserted
with QUORUM, but when I try to read back at QUORUM no data gets returned. However, if I use
the consistency level ONE, I do get results.
> I've dug a bit into this problem, and it appears that internally ThriftServer.getSlice
is finding the column family for the given key, but it's not finding any of the columns, so
thrift doesn't return anything.
> In order to confirm there being a problem, I dropped the RF down to 1 and rebuilt the
cluster. I then reinserted some data, and I can only read data off of one machine.
