[备忘]CDH5.3 Hive FAILED: RuntimeException Cannot create staging directory 报错原因

最近在从CDH5.2升级到CDH5.3后，发现启动Hive执行查询语句时报以下错误：

hive> select count(1) from ht_payment;
FAILED: RuntimeException Cannot create staging directory 'hdfs://lambdafs/user/hive/warehouse/ht_payment/.hive-staging_hive_2015-02-05_11-34-47_062_6721775789378710662-1': Permission denied: user=root, access=WRITE, inode="/user/hive/warehouse/ht_payment":hive:hadoop:drwxr-xr-x

hive> 

但是，同样的语句在CDH5.2集群上是没有问题的，经查，问题是CDH5.3引入的BUG：https://issues.cloudera.org/browse/DISTRO-681

原因在于在创建stage dir的时候，如果是只读权限，那么应该退回到/tmp目录下创建，但是CDH5.3.0未能正确处理这种情况。一个临时的解决方案是，在执行hive语句之前:

set hive.exec.stagingdir=/tmp/hive-staging;
