Package org.apache.drill.exec.store.dfs

Class DrillFileSystem

java.lang.Object
org.apache.hadoop.conf.Configured
org.apache.hadoop.fs.FileSystem
org.apache.drill.exec.store.dfs.DrillFileSystem
All Implemented Interfaces:
Closeable, AutoCloseable, OpenFileTracker, org.apache.hadoop.conf.Configurable, org.apache.hadoop.fs.PathCapabilities, org.apache.hadoop.security.token.DelegationTokenIssuer
public class DrillFileSystem extends org.apache.hadoop.fs.FileSystem implements OpenFileTracker
DrillFileSystem is the wrapper around the actual FileSystem implementation. The DrillFileSystem is immutable. If OperatorStats are provided it returns an instrumented FSDataInputStream to measure IO wait time and tracking file open/close operations.
