卡桑德拉1至卡桑德拉2

Question

我正在嘗試將Cassandra 1升級到Cassandra2。為此，我將Java（升級到Java 7）進行了升級，但是每次執行時：cassandra。 它的啟動是這樣的：

當我嘗試執行時：upgradesstables（nodetool upgradesstables -h 127.0.0.1 -u root ...）我得到了：

Failed to connect to '127.0.0.1:7000': Connexion refusée

有人可以幫我嗎？

謝謝。

Answer 1

盡管我建議使用Oracle，但Cassandra錯誤與OpenJDK無關。

您需要確保您使用的是有效的升級路徑： http : //docs.datastax.com/en/upgrade/doc/upgrade/cassandra/upgradeC_c.html

您無法從早於1.2.9的Cassandra升級到2.0，也無法從1.x升級到2.1，而無需先升級到2.0.7或更高版本。

每個文檔的建議升級路徑：1.x> 1.2.9> 2.0.7> 2.1.x

Answer 2

您的java -version輸出顯示您未使用正確的JDK。 它應該像下面這樣。

Java版本“ 1.8.0_65”
Java（TM）SE運行時環境（內部版本1.8.0_65-b17）
Java HotSpot（TM）64位服務器VM（內部版本25.65-b01，混合模式）

為此，請告訴系統有可用的新Java版本。

$ sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_version/bin/java" 1

使用以下命令將新的JDK設置為默認值：

$ sudo update-alternatives --config java
