I had faced below errors when trying to run current master branch version on jdk8 (build was also on jdk8):
2021-05-26T23:02:20,202 TRACE [RS-EventLoopGroup-1-1] ipc.NettyRpcServer: Connection /192.168.56.105:44592; caught unexpected downstream exception. > java.lang.NoSuchMethodError: java.nio.ByteBuffer.flip()Ljava/nio/ByteBuffer; > at > org.apache.hadoop.hbase.ipc.NettyRpcServerPreambleHandler.channelRead0(NettyRpcServerPreambleHandler.java:48) > ~[hbase-server-3.0.0-SNAPSHOT.jar:3.0.0-SNAPSHOT] > > This specific netty related one happens when RSes try to check into Master, leaving the cluster unusable, but the same NSME happens at other parts of the code too, eventually causing processes to crash. Running on jdk11 fixes it. Anyone else seeing the same? I guess this was not expected, and our official goal is to still support jdk8 for the upcoming 3.0 release?
