[jira] Commented: (CASSANDRA-130) uniform logging of read/write
paths
[ https://issues.apache.org/jira/browse/CASSANDRA-130?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12705674#action_12705674 ]
Eric Evans commented on CASSANDRA-130:
--------------------------------------
As you pointed out on IRC, this needs the following to successfully build:
diff --git a/src/java/org/apache/cassandra/service/StorageProxy.java b/src/java/
index 456b637..ea8ee40 100644
--- a/src/java/org/apache/cassandra/service/StorageProxy.java
+++ b/src/java/org/apache/cassandra/service/StorageProxy.java
@@ -674,7 +674,7 @@ public class StorageProxy implements StorageProxyMBean
// read response
// TODO send more requests if we need to span multiple nodes
- byte[] responseBody = iar.get(DatabaseDescriptor.getRpcTimeout(), T
+ byte[] responseBody = (byte[])iar.get(DatabaseDescriptor.getRpcTime
return RangeReply.read(responseBody).keys;
}
catch (Exception e)
Also, it looks like the patch creates a file named src/java/org/apache/cassandra/db/ColumnFamilyStore.java.orig, and I assume that was unintentional.
It looks possible for the {range,read,write}Operations of StorageProxy to be incremented beyond the limit of an int, (so maybe they should roll over to zero at overflow).
