-
table:{"serde:":"org.apache.hadoop.hive.ql.io.orc.OrcSerde","name:":"default.src_orc_merge_test_part","input
format:":"org.apache.hadoop.hive.ql.io.orc.OrcInputFormat","output
format:":"org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat"}
+ partition:{"ds":"2012-01-03","ts":"2012-01-03+14:46:31"}
+ table:{"name:":"default.src_orc_merge_test_part","input
format:":"org.apache.hadoop.hive.ql.io.orc.OrcInputFormat","output
