I have two problems that confuse me, I have already searched with google,
and dived into the doc of this project, but I can't find proper explains
for them, I need help!
- I use www.aliyun.com cloud compute virtual machine build a
elasticsearch cluster, and I already know that add a now node(in real
server environment) that could auto join in a exist cluster which hold the
same cluster name.
But in my work environment(I use virtual machine and use default "zen
discovery"), I must restart the cluster when I add a new node in this
cluster. Is this necessary?
I have noticed that there are exclusive plugins for google, es2, azure
cloud compute, is cloud compute different real machine? If it is, what
different between them?
- Is there any backup or snapshot mechanism in elasticsearch, because
every midnight (from 2:00-6:00), the performance became lower than daytime
and more likely occur error such as below, should I limit "bulk" operation
in this range of time?
If you know the answer, please explain it for me, Thank you!
the error message!
