Elasticsearch 7.3 upgrade with homebrew

Question

I was using Elasticsearch 6.8 via homebrew, and I was trying to upgrade to 7.3. Previously, on 6.8 I already got a warning about a log file that did not exist, but the server would still run - so I did nothing.

Now with 7.3, I get an error and the server won’t run:

Exception in thread "main" java.lang.RuntimeException: starting java failed with [1]
output:
[0.002s][error][logging] Error opening log file 'logs/gc.log': No such file or directory
[0.002s][error][logging] Initialization of output 'file=logs/gc.log' using options 'filecount=32,filesize=64m' failed.
error:

Invalid -Xlog option '-Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,pid,tags:filecount=32,filesize=64m', see error log for details.

I tried creating the dir/file where elasticsearch was installed, but that did not work for me (or i did something wrong).

I have fixed this by changing the relative logs/gc.log path to an absolute path. Follow the below steps to solve the issue

1. Open jvm.options file which is located at /usr/local/etc/elasticsearch/jvm.options

2. Change the relative path to an absolute path from the following

# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=logs/gc.log:utctime,pid,tags:filecount=32,filesize=64m

to

# JDK 9+ GC logging
9-:-Xlog:gc*,gc+age=trace,safepoint:file=/usr/local/var/log/elasticsearch/gc.log:utctime,pid,tags:filecount=32,filesize=64m

3. Restart elasticsearch $ brew services restart elasticsearch-full or just start it without daemon - $ elasticsearch
