HBase：hbck 无法修复区域不一致

  • 772

我们在 Hadoop 1.0.4 上使用标准的 HBase 0.94.4。HBase 区域之一停留在过渡状态，我在运行时得到以下信息/opt/hbase/bin/hbase hbck：

/opt/hbase/bin/hbase hbck -fix没有解决任何问题，因为它卡在了打印Region still in transition, waiting for it to become assigned错误消息中。 /opt/hbase/bin/hbase hbck -repairHoles也无济于事。我们应该怎么做才能解决这种情况？

hbase

    我们不得不停止 HBase 并删除recovered.edits失败区域的文件夹。hbck在那之后成功了。
