如何在hadoop中释放dfs空间？(how to free dfs space in hadoop?)

我已经清空了hbase中2500万行的列。 我是否需要在表上进行压缩以重新获得hbase中未使用的空间。

当前dfs使用率为93％且无法启动作业。

任何想法如何重获空间？

I have emptied a column from 25 million rows in hbase. Do i need to do compaction on table to regain unused space in hbase.

Current dfs usage is 93% used and unable to launch a job.

Any ideas how to regain space ?

你应该尝试运行一个主要的压缩，看看是否修复它。 您可能还遇到了HBASE-6564问题，该问题已在0.95.0中修复。
