---------------------------------------------------------------
[~alexliu68] I tried to run pig script to load data with CqlNativeStorage but
getting problems, looks like jar conflicts or may be something else can you
please let me know the required jars and their version needed to run
CqlNativeStorage . Below are the things i tried.
1.Applied this patch on top of Cassandra 2.0.07.
2.When i tried to run pig script with CqlNativeStorage it threw me "ERROR
org.apache.pig.tools.grunt.Grunt - ERROR 2998: Unhandled internal error.
com/datastax/driver/core/policies/LoadBalancingPolicy" exception.
3.Then added "cassandra-driver-core-2.0.1.jar" in my classpath after this i
got an exception "ERROR org.apache.pig.tools.pigstats.SimplePigStats - ERROR:
com.codahale.metrics.Metric .......
....
Caused by: java.lang.ClassNotFoundException: com.codahale.metrics.Metric"
4.Then added "metrics-core-3.0.2.jar". After adding this jar file i was able
to run the job but failed and my hadoop log shows me this exception
"Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: All
host(s) tried for query failed (tried: slave1.tpgsi.com/xxxx.yyy.zzz.aa
(com.datastax.driver.core.TransportException: [slave1/xxxx.yyy.zzz.aa] Error
writing))
NOTE: metrics-core-2.2.0.jar already exists in C* 2.0.7 lib folder.
