Hello ! I send you this mail because I have a problem when I try to enable the Ranger plugin for HBase. I have an HDP 2.6.2 (HBase version is 1.1.2) with 500 HBase regionservers and 2 HBase Masters. I have around 100 000 regions in this HBase cluster.
Without Ranger, when I start the cluster, it takes around 20-30 minuts to be started, and then it answers normally. With Ranger enabled for HBase, when I start the cluster, it takes more than an hour to start, and then when I query HBase to scan or to put, I often encounter timeout errors from the regionservers. Is it a known issue that Ranger provoke a performance drop in HBase ? Is there a way to solve this performance problem ? Thank you in advance for your answers. Best regards. Lune
