> While running the random walk test on 10 node cluster the security random
> walk test failed.

> Caused by: org.apache.accumulo.core.client.AccumuloSecurityException: Error
> TABLE_DOESNT_EXIST - Unknown security exception
> at
> org.apache.accumulo.core.client.admin.SecurityOperationsImpl.execute(SecurityOperationsImpl.java:70)

> The test was trying to check permissions on a table, and got an error saying
> that the table did not exist. Looking at the master logs it seems like the
> table was created about 40ms before the check. The hasTablePermission code
> chooses a random tablet server to do the check. I suspect the zoo cache on
> the random tablet server was not yet updated. Many places in the 1.4 code
> have the pattern that if something fails, then clear the cache and retry.
> The code that threw the table not found exception does not do this, but needs
> to. org.apache.accumulo.server.client.ClientServiceHandler.checkTableId() or
> something it calls should clear the cache and retry when it thinks the table
> does not exist.
