Behavioral Changes in HDFS

Behavioral changes denote a marked change in behavior from the previously released version to this version of HDFS.

Cloudera Runtime 7.3.2.10000 SP1

HDFS Offline Image Viewer (oiv) returns non-zero error code on failure: Summary:
The HDFS Offline Image Viewer oiv command now exits with a non-zero status code and displays an error message upon failure instead of returning code 0.; Previous behavior:
Previously, when the oiv command failed due to system-level issues (such as full disks or network errors), it exited with a status code of 0 (success), even if the output file was truncated or incomplete.; New behavior:
Now, the oiv command detects operational failures and exits with a non-zero status code and a descriptive error message, enabling users and automation scripts to reliably detect execution failures.

Improved error handling for HDFS Offline Image Viewer (oiv): Summary:
The HDFS Offline Image Viewer (oiv) command has been updated to correctly report failures when converting an fsimage to CSV.; Previous behavior:
When the oiv command failed due to system-side issues (for example, local filesystem quota exhaustion, disk full, or networking issues), it would exit with code 0 (success). This resulted in truncated or incomplete output files without any indication of failure to the user or automation scripts.; New behavior:
The oiv command now correctly identifies when the output file is incomplete or when a system-level error occurs during processing. In such cases, the command will exit with a non-zero error code and provide an error message, allowing users and scripts to detect the failure.

There are no behavioral changes in this release.
