Is update operation on Hazelcast map thread safe?

I am using Hazelcast distributed map in one of my project. Do I need to use Hazelcast lock explicitly when updating a key from multiple nodes or will it be taken care by Hazelcast implicitly, since Hazelcast docs say IMap is thread safe.

It will take care of it. Every single key always has just one internal thread mutating it and therefore is implicit thread-safe. However if you have multiple operations like get+mutation+put you'll leave the thread-safety. In this cases an EntryProcessor might help you.
