Just a bunch of nits I found skimming through the change. Feel free to address 
in the following changes. Change lgtm.

http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java
File fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java:

http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@281
PS8, Line 281: if (!missingCols.isEmpty()) {
nit: May be easier to read if we invert the condition.

if (missintCols.isEmpty()) return emptyList;


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@286
PS8, Line 286: ");
Add table name?


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@324
PS8, Line 324: ");
table name


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@329
PS8, Line 329: );
table


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@415
PS8, Line 415: ");
table + part name


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@435
PS8, Line 435: );
, tablename?


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@492
PS8, Line 492:     throw new TException(String.format("Invalid response from 
catalogd for request " +
Should we log the exception stack here instead of logging it at all the callers?


http://gerrit.cloudera.org:8080/#/c/11208/8/fe/src/main/java/org/apache/impala/catalog/local/CatalogdMetaProvider.java@689
PS8, Line 689:    * Cache key for the partition list of a table.
nit:For a moment I got confused if there is duplication between this and 
PartitionCacheKey. May be good to clarify that they cache different forms of 
Partition metadata
