[jira] [Updated] (TEZ-1770) Handle ConnectExceptions correctly when establishing connections to an NM which may be down

     [ https://issues.apache.org/jira/browse/TEZ-1770?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Siddharth Seth updated TEZ-1770:

[~rajesh.balamohan] - review please.
Probably a little more complicated than it should be. The timeout math is still done based on unit / connectionTimeout. The patch adds a sleep if the connect attempt fails before the configured timeout. In case of a ConnectError - there's one more retry after sleeping for half the remaining time.
