尝试运行简单的hdfs查询失败:
[ms@cosmosmaster-gi ~]$ hadoop fs -ls /user/ms/def_serv/def_servpath
Java HotSpot(TM) 64-Bit Server VM warning: Insufficient space for shared memory file:
/tmp/hsperfdata_ms/21066
Try using the -Djava.io.tmpdir= option to select an alternate temp location.

未超过您的配额(请参阅下面的命令),但这是群集的问题。现在应该修复。
$ hadoop fs -dus /user/ms
