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 (v6.3.4#6332)
