Project: HBase
Issue Type: Bug
Components: shell
Affects Versions: 1.0.0
Environment: HBase standalone mode on Mac OS X.
Reporter: Lars George
I noticed this on my Mac OS machine:

TABLE
0 row(s) in 0.0260 seconds

hbase(main):004:0> create 'TestTable', 'info'

This should not happen on a case sensitive file system (I presume), so is of
marginal importance. But a simple extra check during directory creation could
fix this.
