Azure HDInsight TLS 1.2 Enforcement

Updated: 13 January, 2020

Starting on 30th June 2020, Azure HDInsight will enforce TLS 1.2 or later versions for all HTTPS connections. We recommend that you ensure that all your clients are ready to handle TLS 1.2 or later versions.

Transport layer security (TLS) and secure sockets layer (SSL) are cryptographic protocols that provide communications security over a computer network (learn more about TLS.). While HDInsight clusters accept TLS 1.2 connections on public HTTPS endpoints, TLS 1.1 is still supported for backward compatibility with older clients.

With the next HDInsight release, you’ll be able to opt-in and configure your new HDInsight clusters to only accept TLS 1.2 connections.
