Hello,guys. help!!! My cluster includes 4 virtual machines(ambari, master, slave1, slave2) which are equipped with : the operating system 'Centos7.2-1511', memory of 4G, and processor 'AMD FX-8350' for each one. I've installed HAWQ using Ambari as follows : - ambari : ambari-server, mysql; - master : HDFS namenode, HDFS datanode, hawq-master, hawq-segment; - slave1 : HDFS datanode, hawq-standby, hawq-segment; - slave2 : HDFS datanode, hawq-segment. After installation, the service hawq-standby could not be started. The error log is as follows : 192.168.86.101 50612 2016-06-30 17:12:51 CST 0 seg-10000 FATAL XX000 semctl(37093455, 11, SETVAL, 0) failed: Invalid argument (pg_sema.c:154) 0 pg_sema.c 154 "Stack trace: 1 0x87448a postgres errstart + 0x22a 2 0x74bb3c postgres <symbol not found> + 0x74bb3c 3 0x7a129f postgres InitProcess + 0x33f 4 0x7affdd postgres PostgresMain + 0x8ad 5 0x763c43 postgres <symbol not found> + 0x763c43 6 0x76439d postgres <symbol not found> + 0x76439d 7 0x7661ce postgres PostmasterMain + 0xc7e 8 0x6c02da postgres main + 0x48a 9 0x7f7ed3881b15 libc.so.6 __libc_start_main + 0xf5 10 0x4a1709 postgres <symbol not found> + 0x4a1709
For more info : i've tried to do the same installation in another cluster. All the equipement is the same, except that the processor is Inter i5-4590. In this situation, all the service could be started without any problem after installation. Do you have any idea ? Thank you in advance. [email protected]
