Testing
-------
Testing done in local
ORC FILE FORMAT in HDFS Ranger Audit log with local audit file store as source for HDFS audit:
NOTE: When this is done each records in the local file will be read for creating the ORC File.
1. Enable Ranger Audit to HDFS in ORC file format using AuditFileQueue
- To enable Ranger Audit to HDFS with ORC format, we need to first enable AuditFileQueue to spool the audit to local first.
* In Namenode host, create spool directory and make sure the path can be read/write/execute for owner of the Service for which Ranger plugin is enabled ( e.g HDFS Service it is hdfs:hadoop, Hive Service it is hive:hadoop ..etc)
$ mkdir -p /var/log/hadoop/audit/staging/spool
$ cd /var/log/hadoop/audit/staging/spool
$ chown hdfs:hadoop spool
* Enable AuditFileQueue via following params in ranger-<component>-audit.xml
xasecure.audit.destination.hdfs.batch.queuetype=filequeue (NOTE: default = memqueue which is the behaviour where a memory queue / buffer is used instead of Local File buffer)
xasecure.audit.destination.hdfs.batch.filequeue.filespool.file.rollover.sec=300 ( This will determine the batch size for ORC file which is created)
xasecure.audit.destination.hdfs.batch.filequeue.filespool.dir=/var/log/hadoop/audit/staging/spool ( This is the local staging directory for audit)
xasecure.audit.destination.hdfs.batch.filequeue.filespool.buffer.size=10000 ( This will determine batch size for ORC file creation alone with rollover.sec parameter)
2. Enable ORC fileformat for Ranger HDFS Audit.
- This is done by having the following param in ranger-<component>-audit.xml. By default the value is "json"
xasecure.audit.destination.hdfs.filetype=orc ( default = json )
3. Provision to control the compression techniques for ORC format. Default is 'snappy'
xasecure.audit.destination.hdfs.orc.compression=snappy|lzo|zlip|none
4. Buffer Size and Stripe Size of ORC file batch. Default is '10000' bytes and '100000' bytes respectively. This will decide the batch size on ORC file in hdfs.
xasecure.audit.destination.hdfs.orc.buffersize= (value in bytes)
xasecure.audit.destination.hdfs.orc.stripesize= (value in bytes)
5. Hive Query to create ORC table with default 'snappy' compresssion.
CREATE EXTERNAL TABLE ranger_audit_event (
repositoryType int,
repositoryName string,
reqUser string,
evtTime string,
accessType string,
resourcePath string,
resourceType string,
action string,
accessResult string,
agentId string,
policyId bigint,
resultReason string,
aclEnforcer string,
sessionId string,
clientType string,
clientIP string,
requestData string,
clusterName string
)
STORED AS ORC
LOCATION '/ranger/audit/hdfs'
TBLPROPERTIES ("orc.compress"="SNAPPY");
-------------------------
JSON FILE FORMAT in HDFS Ranger Audit log with local audit file store as source for HDFS audit:
NOTE: When this is done each local file will be copied entirely into HDFS destination. This enables us to generate Ranger audit files in HDFS which are larger in size which is a preferred.
1. Enable Ranger Audit to HDFS in JSON file format using AuditFileQueue
- To enable Ranger Audit to HDFS with JSON format and local file cached, we need to first enable AuditFileQueue to spool the audit to locally.
* In Namenode host, create spool directory and make sure the path can be read/write/execute for owner of the Service for which Ranger plugin is enabled (e.g HDFS Service it is hdfs:hadoop, Hive Service it is hive:hadoop ..etc)
$ mkdir -p /var/log/hadoop/audit/staging/spool
$ cd /var/log/hadoop/audit/staging/spool
$ chown hdfs:hadoop spool
* Enable AuditFileQueue via following params in ranger-<component>-audit.xml
xasecure.audit.destination.hdfs.batch.queuetype=filequeue ( NOTE: default = memqueue which is the behaviour where a memory queue / buffer is used instead of Local File buffer)
xasecure.audit.destination.hdfs.batch.filequeue.filespool.file.rollover.sec=300 ( This will determine the JSON file size which will be copied to HDFS)
xasecure.audit.destination.hdfs.batch.filequeue.filespool.dir=/var/log/hadoop/audit/staging/spool ( This is the local staging directory for audit)
