Duo Zhang commented on HBASE-16968:
-----------------------------------
StorageType is still placed under org.apache.hadoop.hdfs in hadoop-2.6.x... The
old comment is wrong...
{code}
// StorageType enum is added in hadoop 2.4, but it is moved to another
package in hadoop 2.6 and
// the setter method in OpWriteBlockProto is also added in hadoop 2.6. So we
need to skip the
// setStorageType call if it is hadoop 2.5 or before. See
createStorageTypeSetter for more
// details.
private interface StorageTypeSetter {
OpWriteBlockProto.Builder set(OpWriteBlockProto.Builder builder, Enum<?>
storageType);
}
{code}
Let me fix...

> As we have moved to jdk8, and dropped the support of hadoop-2.4.x and
> hadoop-2.5.x on master, we could use CompletableFuture instead of
> CompletionHandler to make the code more clear, and also remove the support of
> hadoop-2.4.x and hadoop-2.5.x to remove lots of the reflection code.
