[jira] [Commented] (FLINK-33508) Support for wildcard paths in Flink History Server for multi cluster environment

["Anika Kelhanka (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-33508?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17796058#comment-17796058 ] 

Anika Kelhanka commented on FLINK-33508:
----------------------------------------

Approach to update Flink's History Server logic to enable getting logs and data from multiple directories at a time by using a path with wildcards (i.e glob pattern) from HadoopFileSystem locations:

1. Flink's {{HistoryServerArchiveFetcher}} class currently uses the HadoopFileSystem's {{listStatus}} API method which not resolve patterns/wildcards in the history server file path.
2. Introduce a new method {{globStatus(Path pathPattern)}} in {{Flink's FileSystem}} API.
3. Implement new Method in Flink's HadoopFileSystem class such that it internally calls the [Hadoop's globStatus func|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/FileSystem.java#L2217].
4. Finally, point {{HistoryServerArchiveFetcher}} to the new globStatus() API instead of listStatus() for HadoopFileSystem.

> In Cloud users typically create multiple clusters which are ephemeral and want a single history server to look at historical jobs.
> To implement this history server needs to support wildcard paths and this change is to support such wildcard paths
