The buffer size used by a read/write request when streaming data from/to
HDFS.
|
| httpfs.services |
org.apache.hadoop.lib.service.instrumentation.InstrumentationService,
org.apache.hadoop.lib.service.scheduler.SchedulerService,
org.apache.hadoop.lib.service.security.GroupsService,
org.apache.hadoop.lib.service.hadoop.FileSystemAccessService
|
Services used by the httpfs server.
|
| kerberos.realm | LOCALHOST |
Kerberos realm, used only if Kerberos authentication is used between
the clients and httpfs or between HttpFS and HDFS.
This property is only used to resolve other properties within this
configuration file.
|
| httpfs.hostname | ${httpfs.http.hostname} |
Property used to synthetize the HTTP Kerberos principal used by httpfs.
This property is only used to resolve other properties within this
configuration file.
|
| httpfs.authentication.signature.secret.file | ${httpfs.config.dir}/httpfs-signature.secret |
File containing the secret to sign HttpFS hadoop-auth cookies.
This file should be readable only by the system user running HttpFS service.
If multiple HttpFS servers are used in a load-balancer/round-robin fashion,
they should share the secret file.
|
| httpfs.authentication.type | simple |
Defines the authentication mechanism used by httpfs for its HTTP clients.
Valid values are 'simple' or 'kerberos'.
If using 'simple' HTTP clients must specify the username with the
'user.name' query string parameter.
If using 'kerberos' HTTP clients must use HTTP SPNEGO or delegation tokens.
|
| httpfs.authentication.kerberos.principal | HTTP/${httpfs.hostname}@${kerberos.realm} |
The HTTP Kerberos principal used by HttpFS in the HTTP endpoint.
The HTTP Kerberos principal MUST start with 'HTTP/' per Kerberos
HTTP SPNEGO specification.
|
| httpfs.authentication.kerberos.keytab | ${user.home}/httpfs.keytab |
The Kerberos keytab file with the credentials for the
HTTP Kerberos principal used by httpfs in the HTTP endpoint.
|
| httpfs.delegation.token.manager.update.interval | 86400 |
HttpFS delegation token update interval, default 1 day, in seconds.
|
| httpfs.delegation.token.manager.max.lifetime | 604800 |
HttpFS delegation token maximum lifetime, default 7 days, in seconds
|
| httpfs.delegation.token.manager.renewal.interval | 86400 |
HttpFS delegation token update interval, default 1 day, in seconds.
|
| httpfs.hadoop.authentication.type | simple |
Defines the authentication mechanism used by httpfs to connect to
the HDFS Namenode.
Valid values are 'simple' and 'kerberos'.
|
| httpfs.hadoop.authentication.kerberos.keytab | ${user.home}/httpfs.keytab |
The Kerberos keytab file with the credentials for the
Kerberos principal used by httpfs to connect to the HDFS Namenode.
|
| httpfs.hadoop.authentication.kerberos.principal | ${user.name}/${httpfs.hostname}@${kerberos.realm} |
The Kerberos principal used by httpfs to connect to the HDFS Namenode.
|
| httpfs.hadoop.filesystem.cache.purge.frequency | 60 |
