PS6, Line 86: DEFINE_int32_hidden(local_catalog_cache_mb, -1,
            :     "If --use_local_catalog is enabled, configures the size of 
the catalog "
            :     "cache within each impalad. If this is set to -1, the cache 
is auto-"
            :     "configured to 60% of the configured Java heap size. Note 
that the Java "
            :     "heap size is distinct from and typically smaller than the 
overall "
            :     "Impala memory limit.")
IMO, from a end user POV, it is less confusing if this directly exposes the % 
configuration. Something like local_catalog_heap_max_percent...

Given we already have a  max_heap (-Xmx), this would confuse users as to why 
they need to configure two separate values.

Anyway we probably don't expect the customers to change this often, so feel 
free to ignore if that is the case.
