------------------------------------
Summary: Ozone KeyInputStream seek() should not read the chunk file
Key: HDDS-1491
URL: https://issues.apache.org/jira/browse/HDDS-1491
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
KeyInputStream#seek() calls BlockInputStream#seek() to adjust the buffer
position to the seeked position. As part of the seek operation, the whole chunk
is read from the container and stored in the buffer so that the buffer position
can be advanced to the seeked position.
We should not read from disk on a seek() operation. Instead, for a read
operation, when the chunk file is read and put in the buffer, at that time, we
can advance the buffer position to the previously seeked position.
