I am running impala on CDH5.4.3. When i query in impala-shell like select * from <tblname> the results are displaying like some records loading and waiting for some milliseconds and rest of records are loading like that 27000 records are loading like buffering. Performance is poor
I dont know whether it is the problem with cache memory or something..
Please help me out
Thanks in advance
To better suppot you with performance-related issues, we'd appreciate it if you could post the runtime profile of the slow query.
