[jira] [Commented] (ACCUMULO-806) tablet locator fails when the
metadata table has empty sections

Keith Turner commented on ACCUMULO-806:
---------------------------------------
I checked in a fix r1397383 and r1397391
You can easily reproduce this problem in the shell. Below is an example.
{noformat}
root@test15> createtable foo
root@test15 foo> tables -l
!METADATA => !0
foo => 2
trace => 1
root@test15 foo> insert a cf1 cq1 v1
root@test15 foo> addsplits -t !METADATA 2;c 2;f 2;j 2;m 2;r
{noformat}
Exit the shell after doing the above because the location of foo's one tablet is cached. If you start the shell again and scan foo without the patch, it will hang.
