Uses of MRAsyncDiskService in org.apache.hadoop.filecache

Methods in org.apache.hadoop.filecache with parameters of type MRAsyncDiskService
`static Path` | `DistributedCache.getLocalCache(URI cache, Configuration conf, Path baseDir, boolean isArchive, long confFileStamp, Path currentWorkDir, MRAsyncDiskService asyncDiskService)` Get the locally cached file or archive; it could either be previously cached (and valid) or copy it from the `FileSystem` now.
`static Path` | `DistributedCache.getLocalCache(URI cache, Configuration conf, Path baseDir, FileStatus fileStatus, boolean isArchive, long confFileStamp, Path currentWorkDir, boolean honorSymLinkConf, MRAsyncDiskService asyncDiskService)` Get the locally cached file or archive; it could either be previously cached (and valid) or copy it from the `FileSystem` now.
