Denis Magda commented on IGNITE-2391:
-------------------------------------
Lets start reproducing the issue in the following way:
- Prepare Hadoop server nodes with big amount of data in it.
- Let's compare Ignite MR vs Hortonswork MR without IGFS.
- If Ignite MR works better or the same as Hortonswork MR then start debugging
why IGFS slow downs the test. Probably there is an issue in the affinity.
> 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.
> 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.
