Nell'odierno episodio di hbase mi sta riportando alla mia intelligenza abbiamo un problema in cui il master di hbase inizia e poi muore molto rapidamente. Il mio registro master è in questo modo:Hbase master continua a morire, afferma un hbase: lo spazio dei nomi esiste già

ho pensato che questo potrebbe essere qualche residuo di una vecchia corsa così ho cancellato i file nella directory hbases dei dati, la directory zookeepers dati e le mie HDFS. Ho ancora lo stesso errore. Stranamente il mio popper HMaster torna temporaneamente indietro quando ho eseguito stop-hbase.sh anche se non c'era molto che potessi fare.
La mia versione di Hbase è 98,3 e il mio hadoop è 2.2.0. Il mio HBase-site.comf è

EDIT HBase Tentativo org.apache.hadoop.hbase.util.hbck.OfflineMetaRepair, il mio errore è ora HBase file layout needs to be upgraded. You have version null and I want version 8. Is your hbase.rootdir valid? If so, you may need to run 'hbase hbck -fixVersionFile' Che è inutile dal momento che senza padrone hbck non verrà effettivamente eseguito . Modifica modificata Ho imbucato e riavviato il mio dfs e poi ho provato a riparare e riavviare le cose, ora sono tornato dove ho iniziato.
Questo ha cambiato il mio errore almeno. Ora mi dice ATTENZIONE! Il layout del file HBase deve essere aggiornato. Hai versione null e voglio la versione 8. Il tuo hbase.rootdir è valido? In tal caso, potrebbe essere necessario eseguire "hbase hbck -fixVersionFile". che è inutile dal momento che mi manca un master per eseguire hbck su – chenab
E dopo bombardare i miei DFS e quindi eseguire nuovamente lo strumento in linea di riparazione sono tornato dove ho iniziato – chenab
Ebbene si può anche accedere per Zookeeper e rimuovere il dir/HBase (HBase zkcli e rmr la directory/hbase - fai attenzione a non cancellare altro) –
