In application-dev.yml file I have entered the database credentials :
datasource:
type: com.zaxxer.hikari.HikariDataSource
url: jdbc:mysql://localhost:3306/bsadhana?useUnicode=true&characterEncoding=utf8&useSSL=false&useLegacyDatetimeCode=false&serverTimezone=UTC&createDatabaseIfNotExist=true
username: root
password: rxxxx!

Even the jhipster related tables were created in my database. But when I am trying to create a new user it is throwing the above-reported error. is there anywhere else I need to enter these credentials?
The error says your app cannot connect to your Elasticsearch instance, you should make sure you started it with following command as explained in the doc:
docker-compose -f src/main/docker/elasticsearch.yml up
When I try to write a simple table (simpleTable) to MapD, I get the following error:

%python
simpleTable.write.format("jdbc").option("url",
"jdbc:mapd:localhost:8000:mapd:http").option("driver",
JDBC_DRIVER).option("dbtable", "venues").option("user", "mapd").option("password", "<PasswordHere>").save()

When my local pouchdb is performing an initial (i.e. long) replication from a remote couchdb, I sometimes get an Error Code 500 (Database encountered an unknown error) on my client - midway through the replication process.
If I look at the server logs I see :
[error] [<0.1304.0>] Unknown peer: {error,enotconn} for #Port<0.4817>
[error] [<0.1195.0>] Unknown peer: {error,enotconn} for #Port<0.4812>
[error] [<0.1314.0>] Unknown peer: {error,enotconn} for #Port<0.4826>
[error] [<0.1063.0>] Unknown peer: {error,enotconn} for #Port<0.4813>
Anyone seen anything like tis before ?
Restarting the client by closing the tab entirely (sometimes more than once) results in the replication completing successfully.
