Andrey Elenskiy commented on HBASE-16110:
-----------------------------------------
Hello, we are running HBase 2.0.1 with official Hadoop 2.8.4 jars and hadoop
2.8.4 client
(http://central.maven.org/maven2/org/apache/hadoop/hadoop-client/2.8.4/). Got
the following exception on regionserver which brings it down:
```
18/07/02 18:51:06 WARN concurrent.DefaultPromise: An exception was thrown by
org.apache.hadoop.hbase.io.asyncfs.FanOutOneBlockAsyncDFSOutputHelper$13.operationComplete()
java.lang.Error: Couldn't properly initialize access to HDFS internals. Please
update your WAL Provider to not make use of the 'asyncfs' provider. See
HBASE-16110 for more information.
