Error: org.apache.hadoop.util.NativeCodeLoader.buildSupportsSnappy()Z
This means native libs for snappy is not installed properly in hadoop env.
See: http://hadooptutorial.info/snappy-compressiondecompression-tool/
You can
a, Fix the snappy native lib issue in hadoop env.
b, remove snappy config and do not use snappy compress for data in hive
