Subject [jira] Commented: (MAPREDUCE-1466) FileInputFormat should save #input-files in JobConf
Date Mon, 08 Mar 2010 04:25:27 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-1466?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12842534#action_12842534
] 

Amareshwari Sriramadasu commented on MAPREDUCE-1466:
----------------------------------------------------

After MAPREDUCE-849, all library specific configuration parameters are present respective
libraries, not JobContext. For example, FileInputFormat.INPUT_DIR, SPLIT_MAXSIZE, SPLIT_MINSIZE
are configuration for FileInputFormat. So, INPUT_NUM_FILES should also be in FileInputFormat
and its name should be something like mapreduce.input.fileinputformat.numinputfiles

> FileInputFormat should save #input-files in JobConf

> We already track the amount of data consumed by MR applications (MAP_INPUT_BYTES), alongwith,
it would be useful to #input-files from the client-side for analysis. Along the lines of MAPREDUCE-1403,
it would be easy to stick in the JobConf during job-submission.
