rsm | Topic analysis using RSM or PVDM | Topic Modeling library

Controller:

When you have a map with key being the category, and value being a list of items pertaining to that category, you can use this:

There's no way to do that in Elasticsearch with your current data structure.

There are two options:

• Use multi-level nested data structures and model them at indexing time
• Use recursive calls in your application

When connecting to a replica set, the host:port pairs in the connection string are a seedlist.

The driver/client will attempt to connect to each host in the seedlist in turn until it gets a connection.

It then runs the isMaster or hello command to determine which node is primary, and to get a list of all replica set members.

Then it drops the original connection, and attempts to connect to each replica set member using the host and port information retrieved.

The host information returned by the hello command will be the host:port listed in rs.conf(), i.e. the hostnames used to initiate the replica set.

In this usage the driver will only be able to successfully connect using localhost and the local port where the SSH tunnel is listening.

When you pass the replica set name in the connection string, it will connect initially using the locahost/port in the connection string, discover the host:port of all members, and then attempt to connect to each member.

In order to connect to a replica set over SSH tunnel, you would need to have the local machine resolve all of the member hostnames listed in rs.conf() to 127.0.0.1, and open an SSH tunnel for each of those members, using the port number listed in rs.conf() as the local port.

You are in an entity repository, _em should be public.

You could either do:

As it turns out, the simplest solution ist quite often the right one. Storing the data in a data frame df of the same lenght, simple add it using

Thank you @andrewjames I really appreciate your suggestion.

Solved

I have likeCount model in Controller who pass HashMap(K,V)...

Remove iteration and direct get value of this HashMap from parent loop receiver_id() like th:text="${likeCount.get(ExtractListOfSubData.receiver_id)}"...

There are some partial answers on this issue from various places, here is what I think as a complete answer.

• Mongo clients use the hostnames listed in the replica set config, not the seed list

  Although the connection string is "mongodb://localhost:27017,localhost:27018,localhost:27019/?replicaSet=rs", mongo client does not connect to the members of the replica set with seed addresses localhost:27017 etc, instead the client connects to the members in the replica config set returned from the seed hosts, i.e., the ones in the rs.initiate call. This is why the error message is Error connecting to mongo1:27017 instead of Error connecting to localhost:27017.

• Container hostnames are not addressable outside the container network

  A mongo client inside the same container network as the mongo server containers can connect to the server via addresses like mongo1:27017; however, a client on the host, which is outside of the container network, can not resolve mongo1 to an IP. The typical solution for this problem is proxy, see Access docker container from host using containers name for details.

Because the problem involves docker networking and docker networking varies between Linux and Mac. The fixes are different on the two platforms.

The proxy fix (via 3rd party software or modifying /etc/hosts file) works fine but sometimes is not viable, e.g., running on remote CI hosts. A simple self-contained portable solution is to update the intiate_replia_set.sh script to initiate the replica set with member IPs instead of hostnames.
