Steve Loughran updated HADOOP-17491:
------------------------------------
Description:
Azure storage and the abfs client offer recursive listings, but currently
there's no listFiles() method to connect to it instead a recursive treewalk is
used.
Implementing a listFiles(path, recursive) could offer significant speedups to
applications which use it, for example HIVE-24669, and again, async prefetching
could provide even more benefits
Would need changes in
{{org.apache.hadoop.fs.azurebfs.AzureBlobFileSystemStore}} to join everything up
was:
Azure storage and the abfs client offer recursive listings, but currently
there's no listFiles() method to connect to it; instead the base FileSystem
implementation is used, which uses listStatus and treewalks.
Implementing a listFiles(path, recursive) could offer significant speedups to
applications which use it, for example HIVE-24669.
