Hello everyone,
I wonder what is the meaning of hodring.log-destination-uri versus
hodring.log-dir. I'd like to collect MapReduce UI logs after a job has
been run and the only attribute seems to be hod.hadoop-ui-log-dir, in
the hod section.
With that attribute specified, logs are all grabbed in that directory,
producing a large amount of html files. Is there a way to collect them,
maybe as a .tar.gz, in a place somewhere related to the user?
Additionally, how do administrators specify variables in these values?
Which interpreter interprets them? For instance, variables specified in
a bash fashion like $USER in section hodring or ringmaster work well (I
guess they are interpreted by bash itself) but if specified in the hod
section they're not: I tried with
[hod]
hadoop-ui-log-dir=/somedir/$USER
but any hod command fails displaying an error on that line.
Cheers,
Luca
