Why Does RegionServer Fail to Be Started When GC Parameters Xms and Xmx of HBase RegionServer Are Set to 31 GB?

Question

(MRS 3.x and later versions) Check the hbase-omm-*.out log of the node where RegionServer fails to be started. It is found that the log contains An error report file with more information is saved as: /tmp/hs_err_pid*.log. Check the /tmp/hs_err_pid*.log file. It is found that the log contains #Internal Error (vtableStubs_aarch64.cpp:213), pid=9456, tid=0x0000ffff97fdd200 and #guarantee(__ pc() <= s->code_end()) failed: overflowed buffer, indicating that the problem is caused by JDK. How do I solve this problem?

Answer

To rectify the fault, perform the following steps:

Run the su - omm command on a node where RegionServer fails to be started to switch to user omm.
Run the java -XX:+PrintFlagsFinal -version |grep HeapBase command as user omm. Information similar to the following is displayed:
```
uintx HeapBaseMinAddress = 2147483648 {pd product}
```
Change the values of -Xms and -Xmx in GC_OPTS to values that are not between 32G-HeapBaseMinAddress and 32G, excluding the values of 32G and 32G-HeapBaseMinAddress.
Log in to FusionInsight Manager, choose Cluster > Name of the desired cluster > Services > HBase > Instance, select the failed instance, and choose More > Restart Instance to restart the failed instance.
