titan-cassandra mvn test issue on both 0.4.2 and 0.4.3

[mpong...@yahoo.com]

Hi,

On 0.4.2 and 0.4.3, I am experiencing the same issue that an earlier poster had experienced on 0.4.0 when running mvn test on titan-cassandra (see stack trace below).

The titan-cassandra pom.xml already has test jvm opts increased to  -Xmx1280m.   I am wondering why I still seeing this error. 

I even tried raising this to even higher (3G) but still has same problem.

I am on RHEL 5.8 and my box has 8G of mem.

java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

Hi,

   It looks like your glibc is too old for snappy to function properly, can you double check that and upgrade if possible?

Best Regards, Pavel.
