Ryan Wu commented on HDFS-15660:
--------------------------------
In the offline cluster, the namenode version is 3.1.3 and the datanode version
is still 2.6. Also backported this patch. The storage policy of the path
/test/hello.txt is OneSSD.
{code:java}
// [root@yawenzhu-xx-xx-bawen platform]# hdfs storagepolicies -getStoragePolicy
-path /test/hello.txt
The storage policy of /test/hello.txt:
BlockStoragePolicy{ONE_SSD:10, storageTypes=[SSD, DISK],
creationFallbacks=[SSD, DISK], replicationFallbacks=[SSD, DISK]}
{code}
To run count command:
{code:java}
//[root@yawenzhu-xx-xx-bawen platform]# hadoop version Hadoop 2.6.0-cdh5.13.1
This command was run using
/home/vipshop/platform/hadoop-2.6.0-cdh5.13.1-vip-test-proto-20201125-d465552-os6/share/hadoop/common/hadoop-common-2.6.0-cdh5.13.1.jar
[root@yawenzhu-hh-qa-web-bawen platform]# hdfs dfs -count /test/hello.txt 0 1
37 /test/hello.txt{code}
if the datenode do not backport this patch, the count command will throw the
exception. To run count command:
{code:java}
// [root@yawenzhu-xx-xx-bawen platform]# hdfs dfs -count /test/hello.txt

So, if someone need to upgrade from 2.x to 3.x and the cluster enabled
heterogeneous storage , the datanode should backport the patch and then do
upgrade.
> StorageTypeProto is not compatiable between 3.x and 2.6

> In our case, when nn has upgraded to 3.1.3 and dn’s version was still 2.6,
> we found hive to call getContentSummary method , the client and server was
> not compatible because of hadoop3 added new PROVIDED storage type.
