Benjamin Roth commented on CASSANDRA-12905:
-------------------------------------------
I would propose to simply rename the param "isClReplay" in Keyspace.apply() to
"mayThrowWTE" or "mayTimeout" or sth similar with default true. IMHO
"isClReplay" is bad style as the flag should indicate a semantic, not a caller
source.
Keyspace.applyFromCommitLog just has to set writeCommitLog=false + mayTimeout =
false
Introduce Keyspace.applyFromStream and set writeCommitLog=true + mayTimeout =
false
In StreamReceiveTask, the Keyspace could be opened once per SSTableReader, then
the Keyspace wouldn't have to be opened again for every mutation. Like this:
---
for (SSTableReader reader : readers)
{
Keyspace ks =
Keyspace.open(reader.getKeyspaceName());
try (ISSTableScanner scanner = reader.getScanner())
...
if (hasCDC)
ks.applyFromStream(m);
else
ks.applyFromStreamUnsafe(m);

> URL: https://issues.apache.org/jira/browse/CASSANDRA-12905
> Project: Cassandra
> Issue Type: Bug
> Components: Streaming and Messaging
> Environment: centos 6.7 x86_64
> Reporter: Nir Zilka
> Priority: Critical
> Fix For: 3.9
>
>
> Hello,
> I performed two upgrades to the current cluster (currently 15 nodes, 1 DC,
> private VLAN),
> first it was 2.2.5.1 and repair worked flawlessly,
> second upgrade was to 3.0.9 (with upgradesstables) and also repair worked
> well,
> then i upgraded 2 weeks ago to 3.9 - and the repair problems started.
> there are several errors types from the system.log (different nodes) :
> - Sync failed between /xxx.xxx.xxx.xxx and /xxx.xxx.xxx.xxx
> - Streaming error occurred on session with peer xxx.xxx.xxx.xxx Operation
> timed out - received only 0 responses
> - Remote peer xxx.xxx.xxx.xxx failed stream session
> - Session completed with the following error
> org.apache.cassandra.streaming.StreamException: Stream failed
> ----
> i use 3.9 default configuration with the cluster settings adjustments (3
> seeds, GossipingPropertyFileSnitch).
> streaming_socket_timeout_in_ms is the default (86400000).
> i'm afraid from consistency problems while i'm not performing repair.
> Any ideas?
> Thanks,
> Nir.
