Hi,
It was (again) the mistake of the guy in front of the screen... Sorry!
I did not set the "hadoop.tmp.dir" manually: So when I did set it,
as done by you, it works.
So, to be clear, if you'd followed the content of the
http://wiki.apache.org/lucene-hadoop/Hbase/10Minutes faithfully -- 3.1
says set the hadoop.tmp.dir -- do you think things would have just
worked? (We're trying to get our 'getting started' documentation in
order).
Yes. ...when you fully (!) follow the steps - including setting the
haddop.tmp.dir - then it works fine.
BUT then again, the "hadoop-default.xml" contains for
"hadoop.tmp.dir" the value "/tmp/hadoop-${user.name}".
...and this works fine for (actual) Hadoop creating and using (in my
case) the directory "c:\tmp\hadoop-holste".
Does HBase treat the path differently than Haddop?
Hadoop RunJar looks to contain the only use of hadoop.tmp.dir other
than test and contrib code. It does the following: 'new File(new
Configuration().get("hadoop.tmp.dir"));' using java.io.File. In
hbase, its all Path and hadoop FileSystem. So, yes, content of
hadoop.tmp.dir is treated differently.
Could that be changed? ...meaning, wouldn't it be sensible to change
HBase (to use Path etc.) so it behaves like Hadoop?
Did you just change the value of hadoop.tmp.dir from
/tmp/hadoop-${user.name} to /tmp/hadoop-holste on cygwin and it then
worked?
No. I changed it to changed the value "c:\tmp\hadoop-holste".
Also, I tried to do the very same (as described in my intitial mail)
on Ubuntu also *without* specifying "hadoop.tmp.dir".
There it works wihtout problems...
Yeah. I know things work out-of-the-box on linux/macosx. Jim has
been doing a bunch of work trying to get the same to happen on cygwin
(10Minutes has the latest fruit of his work).
As requested by Michel Stack I also attach my log (turned to debug)
when starting the server.
Thanks for the log. Comments interlaced.
Cheers,
Holger
