So when and who call the uninstall function in the service script? ----- Original Message ----- From: "Di Li" <[email protected]> To: [email protected] Sent: Thursday, March 22, 2018 9:17:32 PM Subject: Re: could retry install do uninstall first
First of all, Ambari's "Delete" is more of "unregistering" a component from Ambari's management. It does not remove component binaries. Retry install does not uninstall. In the Ambari paradigm, "adding" a component to a host has three parts, install the binary, config, start. The "install" option on the host menu calls the install method of that component to install the binary and local config (you should try to make the config step idempotent).
