Environment

    MapR Versions 3.1, 3.1.1, 4.0.0, and 4.0.1.
    Safari Versions 7.0 and higher.
    Chrome Versions 39.0 and higher.

 

Symptom

When a user attempts to login to the Mapr Control System (MCS), the attempt fails with the following exception in /opt/mapr/logs/adminuiapp.log

javax.net.ssl.SSLHandshakeException: no cipher suites in common at 
sun.security.ssl.Alerts.getSSLException(Alerts.java:192) at
sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1884) at
sun.security.ssl.Handshaker.fatalSE(Handshaker.java:276) at

 

Root Cause

Recent versions of Safari and Chrome web browsers have removed support for older certificate cipher algorithms, including those used by some versions of MapR. Because of this, users of these new browser versions may lose the ability to log into MapR Control System (MCS).

 

Solution

A fix for this issue is available in MapR Versions 4.0.2 and later. Existing clusters can be patched to workaround this issue. Please follow the doc
