> Executing a DROP DATABASE statement with the CASCADE option does not clear the cache directives associated with the cached tables that are contained in the dropped database. 
> To reproduce:
> {code}
> impala> create database foo;
> impala> use foo;
> impala>create table t1 (a int) cached in 'testPool' with replication = 8;
> shell> hdfs cacheadmin -listDirectives
> impala> use default;
> impala> drop database foo cascade;
> shell> hdfs cachedmin -listDirectives <-- the output contains the directive associated with the path of table t1
> {code}
> This has been breaking impala-cdh5.5.x-repeated-runs (https://issues.cloudera.org/browse/IMPALA-2510)
