------------------------------------------------
FRom hcat-user mailing list:
I started webhcat server using sbin/webhcat_server.sh start.
Problem:
---------
Later when I sent the **first** curl request, I got HTTP error 500 with
ClassNotFound exception "org/codehaus/jackson/map/deser/std/StdDeserializer".
However, immediately after this, if I sent the same request for the *second*
time, it started working fine.
More explanations of the command-used and the associated error messages both in
client and server sides are pasted at the end.
My Workaround:
-----------
After different tries, I was able to solve the problem as follows:
1. In $HCAT_HOME/share/webhcat/svr/lib, I found the
jackson-mapper-asl-1.8.3.jar there. I replaced it with a newer version
jackson-mapper-asl-1.9.2.jar.
2. Restart webhcat server.
3. Submit (the first time failure ) curl command. And it worked without any
problem from the beginning.
Btw, I got the resolution hints from the internet proposed for different
product.
Question:
--------
Should we use jackson.version 1.9.2 instead of 1.8.3?
If yes, I could create a JIRA and send a patch.
Or am I missing something obvious?
