This update disables those two commands by default. The new configuration option "4lw.commands.whitelist" can be used to whitelist commands selectively (and the full set of commands can be restored with '*') For the stable distribution (jessie), this problem has been fixed in version 3.4.5+dfsg-2+deb8u2. For the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your zookeeper packages.
