[jira] [Commented] (CASSANDRA-3369) AssertionError when adding a node and doing repair, repair hangs

    [ https://issues.apache.org/jira/browse/CASSANDRA-3369?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13128541#comment-13128541 ] 

Christian Spriegel commented on CASSANDRA-3369:
-----------------------------------------------

Update: I also had problems because I was using Defalte compression, which seems to be broken. The AssertionError during repair still occurs with Snappy Compression.

> Hi again,
> I was playing aroung with Cassandra 1.0.0-rc2 and got an AssertionError. The cluster I set up was two cassandra nodes on one laptop using different 127.0.0.* loopback devices. Both nodes have separate folders on the harddisk.
> Here is what I did:
> 1. Started node1 and inserted some data into it using a simple singlethreaded testprogram (uses hector 0.8.0-2):
> 127.0.0.1       datacenter1 rack1       Up     Normal  583.55 MB       100.00% Token(bytes[63e5b6995466cd3221cba16646ae19ed])
> 2. I started another node, node 2 = 127.0.0.2:
> 127.0.0.2       datacenter1 rack1       Up     Normal  147.57 KB       50.00%  Token(bytes[4d6ccfeaa8bb59551751a2816fde9343])
> 127.0.0.1       datacenter1 rack1       Up     Normal  583.55 MB       50.00%  Token(bytes[63e5b6995466cd3221cba16646ae19ed])
> 3. I triggered a "nodetool -h 127.0.0.1  repair" on the first node that had the data from my test.
> This repair does not seem to ever end. The nodetool is hanging now but my computer is idle. I get an AssertionError on the first node:
> java.lang.AssertionError

> create keyspace Test with placement_strategy = 'org.apache.cassandra.locator.SimpleStrategy' and strategy_options = {replication_factor:2};
> CREATE COLUMN FAMILY Response WITH key_validation_class=BytesType AND compression_options={sstable_compression:DeflateCompressor};
> kind regards,
