If the property set to true, insecure communication among H2O nodes is allowed for the XGBoost algorithm.
Automatically generate key store for H2O Flow SSL
This option can be set either to "internal" or "external" When set to "external" H2O Context is created by connecting to existing H2O cluster, otherwise it creates H2O cluster living in Spark - that means that each Spark executor will have one h2o instance running in it.
This option can be set either to "internal" or "external" When set to "external" H2O Context is created by connecting to existing H2O cluster, otherwise it creates H2O cluster living in Spark - that means that each Spark executor will have one h2o instance running in it. The internal is not recommended for big clusters and clusters where Spark executors are not stable.
Interval used to ping and check the H2O backend status.
Extra properties passed to H2O client during startup.
Allows to override the base URL address of Flow UI, including the scheme, which is showed to the user.
Location of iced directory for the driver instance.
IP of H2O client node
Location of log directory for the driver instance.
H2O log level for client running in Spark driver
Subnet selector for H2O client - if the mask is specified then Spark network setup is not discussed.
Port on which H2O client publishes its API.
Port on which H2O client publishes its API. If already occupied, the next odd port is tried and so on
Print detailed messages to client stdout
Exact client port to access web UI.
Exact client port to access web UI.
The value -1
means automatic search for free port starting at spark.ext.h2o.port.base
.
Configuration property - name of H2O cloud
Configuration property - timeout for cloud up.
Enable/Disable listener which kills H2O when there is a change in underlying cluster's topology *
H2O's URL context path
Timeout in milliseconds specifying how often the H2O backend checks whether the Sparkling Water client (either H2O client or REST) is connected
Enable/Disable exit on unsupported Spark parameters.
Path to flow dir.
Extra http headers for Flow UI
Decide whether Scala cells are running synchronously or asynchronously
Number of max parallel Scala cell jobs.
Enable hash login.
The full address of HiveServer2, for example hostname:10000
Can be used to further customize the way the driver constructs the Hive JDBC URL
Hiveserver2 Kerberos principal, for example hive/hostname@DOMAIN.COM
Authorization token to Hive
Offset between the API(=web) port and the internal communication port; api_port + port_offset = h2o_port
Secure internal connections by automatically generated credentials
Path to Java KeyStore file.
Alias for certificate in keystore to secure Flow
Password for Java KeyStore file.
If enabled, H2O instances will create JDBC connections to a Kerberized Hive so that all clients can read data from HiveServer2.
If enabled, H2O instances will create JDBC connections to a Kerberized Hive so that all clients can read data from HiveServer2. Don't forget to put a jar with Hive driver on spark classpath if the internal backend is used.
Enable Kerberos login.
Enable LDAP login.
Login configuration file.
If a scoring MOJO instance is not used within a Spark executor JVM for a given timeout in milliseconds, it's evicted from executor's cache.
Extra properties passed to H2O nodes during startup.
Location of log directory for remote nodes.
H2O internal log level for launched remote nodes.
Subnet selector for H2O nodes running inside executors - if the mask is specified then Spark network setup is not discussed.
Configuration property - base port used for individual H2O nodes configuration.
Set how often in seconds stack traces are taken on each h2o node.
Set how often in seconds stack traces are taken on each h2o node. -1 represents that the stack traces are not collected.
Limit for number of threads used by H2O, default -1 means unlimited
Password for the client authentication.
Enable/Disable Sparkling-Water REPL *
Timeout for Rest API requests
Number of executors started at the start of h2o services, by default 1
Enable/Disable check for Spark version.
Path to Java KeyStore file used for the internal SSL communication.
User name for cluster and the client authentication.
Whether certificates should be verified before using in H2O or not.
