Hello,    We've recently migrated CDH from 5.16.2 to 6.3.3 and we now have the following message when we create a table using Impala JDBC driver (we are using the latest version 2.6.15.1017). errorMessage:ImpalaRuntimeException: Error creating Kudu table 'impala::pdo.discoveries' CAUSED BY: IllegalArgumentException: table owner must not be null or empty   When the same "create table" statement is executed in impala-shell, it works perfectly well. The search for this error message in google did not find much result.   Any idea about the root cause ?   ... View more

Hello,   We are retrieving the state of a Spark application in yarn using the Cluster Application API (http://rm-http-address:port/ws/v1/cluster/apps/{appid})   Since I've migrated CDH from 5.16.2 to 6.3.3, the response returned by this API looks invalid as it contains a duplicate key "entry" under the "resourceSecondsMap" as shown below. {    "app":{       "id":"application_1582735008785_0001",       "user":"ossa",       "name":"Labeling 2.0.0.0SNAPSHOT",       "queue":"root.inta-pdo.labeling",       "state":"FINISHED",       "finalStatus":"SUCCEEDED",       "progress":100.0,       "trackingUI":"History",       "trackingUrl":"http:// myhost :8088/proxy/application_1582735008785_0001/",       "diagnostics":"",       "clusterId":1582735008785,       "applicationType":"SPARK",       "applicationTags":"",       "priority":0,       "startedTime":1582742735767,       "launchTime":1582742737578,       "finishedTime":1582742815272,       "elapsedTime":79505,       "amContainerLogs":"http:// myhost :8042/node/containerlogs/container_1582735008785_0001_01_000001/ossa",       "amHostHttpAddress":" myhost :8042",       "amRPCAddress":" myIP ",       "allocatedMB":-1,       "allocatedVCores":-1,       "reservedMB":-1,       "reservedVCores":-1,       "runningContainers":-1,       "memorySeconds":1908208,       "vcoreSeconds":827,       "queueUsagePercentage":0.0,       "clusterUsagePercentage":0.0,       "resourceSecondsMap":{          "entry":{             "key":"memory-mb",             "value":"1908208" },          "entry":{             "key":"vcores",             "value":"827" } },       "preemptedResourceMB":0,       "preemptedResourceVCores":0,       "numNonAMContainerPreempted":0,       "numAMContainerPreempted":0,       "preemptedMemorySeconds":0,       "preemptedVcoreSeconds":0,       "preemptedResourceSecondsMap":{ },       "logAggregationStatus":"SUCCEEDED",       "unmanagedApplication":false,       "amNodeLabelExpression":"",       "timeouts":{          "timeout":[             {                "type":"LIFETIME",                "expiryTime":"UNLIMITED",                "remainingTimeInSeconds":-1 } ] } } } As far as I know this kind of structure is considered as invalid with respect to the JSON format and I cannot initialize a java JSONObject with this content (I would receive a  IOException :  Duplicate key "entry" at 992 [character 993 line 1])   Is there any way to workaround this problem ? ...
