本文介绍了解决HBase中出现的Foundlingeringreference异常的方法。通过删除HDFS中残留的引用文件来修复失败的Region分裂问题，并确保Region能够被自动重新分配。文章还提供了具体的命令操作步骤。

Found lingering reference异常

第一种解决：hbase hbck -fixReferenceFiles month_hotstatic

另一种方法：

This looks like you had a failed region split, see [HBASE-8052] (https://issues.apache.org/jira/browse/HBASE-8502) for more details.

This bug leaves references to parent regions that have been moved in HDFS. To fix, just delete the reference files listed in the HBCK output e.g. hadoop fs -rm hdfs://master:8020/hbase/LogTable/f41ff2fae25d1dab3f16306f4f995369/l/d9c7d33257ae406caf8d94277ff6d247.fbda7904cd1f0ac9583e04029a138487.

Once the bad references are gone the region should be assigned automatically. You may have to do the assignment from the shell, in my experience though it only takes a minute or two for the region to get reassigned. Then run hbase hbck -fix again to confirm there are no other inconsistencies.

hbase hbck > 1.log 2>&1

cat 1.log | grep -i "ERROR"

cat 1.log | grep -i "ERROR" | awk -F"ERROR: Found lingering reference file " '{print $2}' >a.txt

#!/bin/sh

while read line
do
hadoop fs -rmr $line

done < a.txt
