> Dropping partitions from a table fails with a misleading error message saying that "partition not found":
> {code}
> 0: jdbc:hive2://nightly-71x-zx-1.nightly-71x-> alter table t1p drop partition (p1>0);
> Error: Error while compiling statement: FAILED: SemanticException [Error 10006]: Partition not found (p1 > 0) (state=42000,code=10006)
> {code}
> however the partitions exist, the real error message is visible in the HiveServer2 logs:
> {code}
> Caused by: MetaException(message:Number of partitions scanned (=2) on table 't1p' exceeds limit (=1). This is controlled on the metastore server by hive.metastore.limit.partition.request.)
> 	at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$get_partitions_by_expr_result$get_partitions_by_expr_resultStandardScheme.read(ThriftHiveMetastore.java) 
> ...
> {code}
> Hive should surface the real error message to the user, that the "hive.metastore.limit.partition.request" limit has been reached.
> This happens only when "hive.metastore.limit.partition.request" is set.
> Haven't verified other types of queries, potentially other queries fail similarly.
