FSDataInputStreamWrapper fsdis,
long size,
CacheConfig cacheConf,
org.apache.hadoop.conf.Configuration conf)
The sockets and the file descriptors held by the method parameter
FSDataInputStreamWrapper passed will be freed after its usage so caller needs to ensure
that no other threads have access to the same passed reference. |
