+  <!-- This field is instance of BlockBlobInputStream and read(long, byte[], int, int)
+  calls it's Super class method when 'fs.azure.block.blob.buffered.pread.disable'
+  is configured false. Super class FSInputStream's implementation is having
+  proper synchronization.
+  When 'fs.azure.block.blob.buffered.pread.disable' is true, we want a lock free
+  implementation of blob read. Here we don't use any of the InputStream's
+  shared resource (buffer) and also don't change any cursor position etc.
+  So its safe to go with unsynchronized way of read. -->
