> DatanodeManager does not handle null storage type properly
> ----------------------------------------------------------
>
> Key: HDFS-17098
> URL: https://issues.apache.org/jira/browse/HDFS-17098
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: ConfX
> Priority: Critical
> Attachments: reproduce.sh
>
>
> h2. What happened:
> Got a {{NullPointerException}} without message when sorting datanodes in
> {{{}NetworkTopology{}}}.
> h2. Where's the bug:
> In line 654 of {{{}DatanodeManager{}}}, the manager creates a second sorter
> using the standard {{Comparator}} class:
> {noformat}
> Comparator<DatanodeInfoWithStorage> comp =
> Comparator.comparing(DatanodeInfoWithStorage::getStorageType);
> secondarySort = list -> Collections.sort(list, comp);{noformat}
> This comparator is then used in {{NetworkTopology}} as a secondary sort to
> break ties:
> {noformat}
> if (secondarySort != null) {
> // a secondary sort breaks the tie between nodes.
> secondarySort.accept(nodesList);
> }{noformat}
> However, if the storage type is {{{}null{}}}, a {{NullPointerException}}
> would be thrown since the default {{Comparator.comparing}} cannot handle
> comparison between null values.
> h2. How to reproduce:
> (1) Set {{dfs.heartbeat.interval}} to {{{}1753310367{}}}, and
> {{dfs.namenode.read.considerStorageType}} to {{true}}
> (2) Run test:
> {{org.apache.hadoop.hdfs.server.blockmanagement.TestSortLocatedBlock#testAviodStaleAndSlowDatanodes}}
> h2. Stacktrace:
> {noformat}
> java.lang.NullPointerException
