---------------------------------------
Summary: Exception in Tracing
Key: PHOENIX-1226
URL: https://issues.apache.org/jira/browse/PHOENIX-1226
Project: Phoenix
Issue Type: Bug
Affects Versions: 4.1
Environment: 0.98.5 hbase, 4.1.0 phoenix
Reporter: Dan Di Spaltro
I was exposed to an exception in the tracing code, during my test setup of
Phoenix in the following code:
{code}
58062 [defaultRpcServer.handler=2,queue=0,port=53950] WARN
org.apache.hadoop.ipc.RpcServer -
defaultRpcServer.handler=2,queue=0,port=53950: caught:
java.lang.IllegalArgumentException: offset (0) + length (4) exceed the capacity
of the array: 3

{code}
It is related to the following line of code where we interpret all KV
annotation values as byte-wise integers here:
https://github.com/apache/phoenix/blob/v4.1.0/phoenix-hadoop-compat/src/main/java/org/apache/phoenix/trace/TracingCompat.java#L56
Here is where HBase is adding a non-integer KV annotation:
https://github.com/apache/hbase/blob/0.98.5/hbase-server/src/main/java/org/apache/hadoop/hbase/ipc/RequestContext.java#L105
The fix should be simple, but I am not aware of all the related issues in
changing this.
