Ravi Gummadi commented on MAPREDUCE-1979: ----------------------------------------- ant test and test-patch passed on my local machine. > "Output directory already exists" error in gridmix when > gridmix.output.directory is not defined > ----------------------------------------------------------------------------------------------- > > Key: MAPREDUCE-1979 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1979 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: contrib/gridmix > Reporter: Ravi Gummadi > Assignee: Ravi Gummadi > Attachments: 1979.patch, 1979.v1.1.patch, 1979.v1.2.patch, > 1979.v1.3.patch, 1979.v1.patch > > > "Output directory already exists" error is seen in gridmix when > gridmix.output.directory is not defined. When gridmix.output.directory is not > defined, then gridmix uses inputDir/gridmix/ as output path for gridmix run. > Because gridmix is creating outputPath(in this case, inputDir/gridmix/) at > the begining, the output path to generate-data-mapreduce-job(i.e. inputDir) > already exists and becomes error from mapreduce. > There is need for creation of this outputPath in any case(whether user > specifies the path using gridmix.output.directory OR gridmix itself > considering inputDir/gridmix/ ) even though the paths are automatically > created for output paths of mapreduce jobs(like mkdir -p), because gridmix > needs to set 777 permissions for this outputPath sothat different users can > create different output directories of different mapreduce jobs within this > gridmix run. > The other case in which this problem is seen is when gridmix.output.directory > is defined as a relative path. This is because in this case also, gridmix > tries to create relative path under ioPath/ and thus the same issue. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
