Hi,
We did not face this issue in our previous version of HBase-1.4.x (hadoop-2.7.3). We recently upgraded our cluster to hbase-2.1.9(hadoop-3.1.3) and enabled erasure coding policy (XOR-2-1-1024k) for testing purpose. We faced the issue mentioned in the following JIRA when one of the datanode went unreachable state. https://issues.apache.org/jira/browse/HDFS-14175 We applied the patch and fixed it. I guess we are facing this issue after this . Also hbck2 filesystem report looks fine. Regards, Meeran. ---- On Sat, 04 Jul 2020 09:02:06 +0530 zheng wang <[email protected]> wrote ---- Hi, "cur=10259783_1010157000000008851/hb:B/1490097148981/Put/vlen=16591695" "Invalid onDisksize=-969694035: expected to be at least 33 and at most 2147483647, or -1" I guess there is a very big cell cause the block size exceed the Integer.MAX_VALUE, and lead to overflow error. ------------------ 原始邮件 ------------------ 发件人: "Mohamed Meeran"<mailto:[email protected]>; 发送时间: 2020年7月3日(星期五) 晚上10:26 收件人: "user"<mailto:[email protected]>; 主题: Could not iterate StoreFileScanner - during compaction Hi, We are using HBase-2.1.9 (Hadoop-3.1.3) in our setup.
