[jira] [Created] (IGNITE-2391) IGFS + Ignite MR works slower than Hadoop (Hortonswork) MR

Denis Magda created IGNITE-2391:
-----------------------------------

             Summary: IGFS + Ignite MR works slower than Hadoop (Hortonswork) MR
                 Key: IGNITE-2391
                 URL: https://issues.apache.org/jira/browse/IGNITE-2391
             Project: Ignite
          Issue Type: Bug
          Components: IGFS
    Affects Versions: 1.5
            Reporter: Denis Magda
            Priority: Blocker
             Fix For: 1.6


A performance test of IGFS MR vs Traditional HDFS (Hortonswork) MR and performance here was actually worse using IGFS MR (quite shockingly)

5 ignite nodes on the 5 data nodes were setup, each also with 64GB ram.

The same sample search via Hunk was done, making sure Hunk initiated the MR stage. The only change in both runs was only to run IGFS MR or Traditional MR over HDFS
 
Traditional MR over HDFS.
This search has completed in 54.701seconds.

IGFS MR
This search has completed in 75.959seconds.
