[Resolved]Elasticsearch won't startup without any information in the log


#1

the background is on my this server elasticsearch 2.4.0 was running all the way without problem and i tried to upgrade to 5.0.0 but failed, so i want to revert back to 2.4.0.

i uninstall 5. 0.0 and install back 2.4.0, elasticsearch can never startup, it shows starting elasticsearch ok but dead immediately, below are the only information in the log, it should not be the reason why it cant startup because I have another server running fine with same error also.

[2016-10-28 12:04:10,660][WARN ][bootstrap ] unable to install syscall filter: seccomp unavailable: requires kernel 3.5+ with CONFIG_SECCOMP and CONFIG_SECCOMP_FILTER compiled in

can anyone help?
