Vladimir Ozerov updated IGNITE-3167: ------------------------------------ Fix Version/s: (was: 2.0) 2.1 > Hadoop: restore external execution. > ----------------------------------- > > Key: IGNITE-3167 > URL: https://issues.apache.org/jira/browse/IGNITE-3167 > Project: Ignite > Issue Type: Task > Components: hadoop > Affects Versions: 1.5.0.final > Reporter: Vladimir Ozerov > Priority: Critical > Fix For: 2.1 > > > Some time ago we decided to get rid external execution mode. It appears to be > a wrong decision. > Hadoop users rely on its process-per-job nature in lot's places. One of such > case could be observed in HiBench Bayes benchmark: > 1) Job creates something in the local file system through Hadoop FileSystem > API. > 2) Then it tries to get this data using regular java.io.FileReader and > relative paths. > This doesn't work in embedded mode because our LocalFileSystem wrapper > assigns different work dirs for jobs, but process-wide working directory is > always the same. As a result, aforementioned benchmark doesn't work in > Ignite, but work with standard Hadoop job tracker. > It seems that we must return external execution back. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
