Description

When attempting a map reduce over a table, I got the warning Unable to locate bins for specified ranges. Retrying. from InputFormatBase. It would keep retrying until I got bored and killed the job, never finding the correct bins.

I logged in to the Accumulo shell and was able to fully scan the !METADATA table without a problem. However, when I try to scan my data table (id: a), I saw the following messages repeated with debug on:

[impl.MetadataLocationObtainer] TRACE: tid=11 oid=7  Looking up in !0 row=a; extent=!0;~;!0< tserver=[ip address]:9997
[impl.MetadataLocationObtainer] TRACE: tid=11 oid=7  Got 0 results from !0;~;!0< in 1.003 secs
[impl.TabletLocatorImpl] TRACE: tid=11 oid=4  Located tablet null at null in 1.058 secs
[impl.ThriftScanner] DEBUG: Failed to locate tablet for table : a row :

I was able to work around this problem by cloning the table and using the cloned version.
