Description

Master detector uses the following ACL regardless of auth credentials:

static ACL _EVERYONE_READ_CREATOR_ALL_ACL[] = {

{ZOO_PERM_READ, ZOO_ANYONE_ID_UNSAFE}

,

{ZOO_PERM_ALL, ZOO_AUTH_IDS}

};

But this ACL doesn't work with the (default) ZK server when there are no auth credentials provided.

2 ways to fix this:

1) Short term: Start the java ZK server with the flag "-Dzookeeper.skipACL=yes"

2) Long term: Fix the detector code, to use a different ACL (ZOO_OPEN_ACL_UNSAFE) when no auth is provided. This is what the new replicated log does.
