bshashikant opened a new pull request #82: HDDS-2359. Seeking randomly in a key with more than 2 blocks of data leads to inconsistent reads URL: https://github.com/apache/hadoop-ozone/pull/82 ## What changes were proposed in this pull request? The issue was primarily caused when first seek to an offset , then read followed by seek to a different offset and read data again both containing overlapping set of chunks . Once a seek to a position is done, the chunkPosition inside each blockInputStream is not correctly set to 0 thereby, the 1st which to which the seek offset belongs is correctly read but for the next subsequent chunks , data to be read will be returned as zero as a result of which , all the read for the subsequent chunks will return length to be read as 0. The solution here is to reset all the subsequent chunks for all subsequent blocks after a seek to set to 0 so once that it will start read from the beginning of each chunk. ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-2359 ## How was this patch tested? The patch was tested with addition of unit tests which reliably reproduce the issue. This was also deployed in real cluster where the issue was first discovered and verified. Thanks @fapifta for discovering the issue and help verifying the fix as well. Thanks @bharatviswa504 and @hanishakoneru for the contribution in the fix provided.
