Subject TestShell and shell issues.
Date Sat, 16 Mar 2013 02:07:57 GMT
I faced some issues today when running the TestShell.

I tried the shell too and it's not working.

Based on the logs, HBase seems to be working fine, but the shell is not

jmspaggi@hbasetest:~/hbase/hbase-0.94.6$ bin/hbase shell
java.lang.RuntimeException: java.lang.UnsatisfiedLinkError:
/run/shm/tmp/jffi7682189782786951905.tmp: failed to map segment from
shared object: Operation not permitted
	at com.kenai.jffi.Foreign$InValidInstanceHolder.getForeign(Foreign.java:90)
	at com.kenai.jffi.Foreign.getInstance(Foreign.java:95)
	at com.kenai.jffi.Library.openLibrary(Library.java:151)

Which is strange since I'm able to access this file:

jmspaggi@hbasetest:~/hbase/hbase-0.94.6$ touch

Regarding the rights on the directory:
jmspaggi@hbasetest:~/hbase/hbase-0.94.6$ ll /run/shm/
total 0
drwxrwxrwx 20 root root 500 mar 15 21:57 tmp

The shell entire strack trace is available there: http://pastebin.com/bW85UNKb

My tmp folder is mapped to /run/shm to increase perfomances and there
is 8GB available on this tmp drive. So it's not a disk space issue.

If I remove the mapping to the memory drive and I use the hard drive
for the tmp folder,

So something is not working on a memory drive, and I think it's more
related to Ruby than HBase...
