Dear Alluxio users,
We are excited to announce the release of Alluxio 2.8.1! This patch includes a multitude of fixes and feature improvements, with highlights being:
ALLUXIO STABILITY ENHANCEMENT
Alluxio 2.8.1 added new test frameworks and conducted comprehensive system testing. A bunch of system vulnerabilities has been detected and fixed:
ALLUXIO POSIX API ENHANCEMENT
Alluxio 2.8.1 ran a bunch of functionality verification and data correctness tests and fixed a bunch of issues found including Alluxio POSIX API in Kubernetes high resource consumption issue (2f7cc8e), Fuse rename behavior mismatch with Linux (938a92), FIO failure (49ae5d0), truncate issue (370984), Fuse user group issue (fccd691), unmount pid (34d46), open flag (65a151), remove directory error code (e54b911), write then overwrite (001ee73) and etc.
NEW ALLUXIO CSI DRIVER
Alluxio CSI driver can mount Alluxio into application containers and thus applications can access data stored in Alluxio or UFSes through the mounted path.
CSI can couple the life cycle of applications and Alluxio Fuse processes to avoid unneeded waste of resources to keep AlluxioFuse processes always running. Only when application pods are ready will the AlluxioFuse processes be launched.
The new Alluxio CSI driver implementation further supports starting the AlluxioFuse process in its own pod. The lifecycle of the Fuse process can thus be independent from CSI Nodeserver to improve its stability. See CSI documentation for more information about Alluxio CSI driver and how to enable this functionality.
IMPROVE ALLUXIO METRICS
Alluxio 2.8.1 further improves the Alluxio metrics for better monitoring the Alluxio system.
