Question

我没有太多成功搞清楚这个错误信息的含义。我也是HDFS和HBase的新手，所以这是问题的一部分。除了HDFS服务器空间不足的可能性之外，可能会导致此错误：

Answer 1

您可以通过fsck查看HDFS的状态（并修正错误），请参阅http://hadoop.apache.org/docs/r2.4.0/hadoop-project-dist/hadoop-common/CommandsManual.html#fsck

完成后，您可以使用hbck查看HBase的状态，请参阅http://hbase.apache.org/book/hbck.in.depth.html

Answer 2

问题是该特定HDFS节点上缺少磁盘空间。

Hbase在HDFS日志问题上爆炸
