Subject Spark sql thrift server slower than hive
Date Sun, 22 Mar 2015 10:38:12 GMT
We have cloudera CDH 5.3 installed on one machine.

We are trying to use spark sql thrift server to execute some analysis
queries against hive table.

Without any changes in the configurations, we run the following query on
both hive and spark sql thrift server

*select * from tableName;*

The time taken by spark is larger than the time taken by hive which is not
supposed to be the like that.

The hive table is mapped to json files stored on HDFS directory and we are
using ** for

Why spark takes much more time to execute the query than hive ?
